+Overview
+	
+    Provides a mechanism for DrawPixels and ReadPixels to efficiently
+    transfer depth and stencil image data.  Specifically, we defined new
+    packed pixel formats and types which pack both stencil and depth
+    into one value.
+
+Issues:
+
+    1. Is this the right way to distinguish between 24/8 and 8/24
+       pixel formats?  Should we instead provide both:
+	
+       GL_DEPTH_STENCIL_MESA
+       GL_STENCIL_DEPTH_MESA
+
+       And perhaps just use GL_UNSIGNED_INT, GL_UNSIGNED_SHORT ?
+
+    2. If not, is it correct to use _REV to indicate that stencil
+       preceeds depth in the 1_15 and 8_24 formats?
+
+    3. Do we really want the GL_UNSIGNED_SHORT formats?

+
+Overview
+	
+    This extension modifies the way in which points are rendered,
+    specifically when they're textured.  When SPRITE_POINT_MESA is enabled
+    a point is rendered as if it were a quadrilateral with unique texture
+    coordinates at each vertex.  This extension effectively turns points
+    into sprites which may be rendered more easily and quickly than using
+    conventional textured quadrilaterals.
+
+    When using point size > 1 or attenuated points this extension is an
+    effective way to render many small sprite images for particle systems
+    or other effects.
+
+Issues:
+
+    1. How are the texture coordinates computed?
+
+       The lower-left corner has texture coordinate (0,0,r,q).
+       The lower-right, (1,0,r,q).  The upper-right, (1,1,r,q).
+       The upper-left, (0,1,r,q).
+
+    2. What about texgen and texture matrices?
+
+       Texgen and the texture matrix have no effect on the point's s and t
+       texture coordinates.  The r and q coordinates may have been computed
+       by texgen or the texture matrix.  Note that with a 3D texture and/or
+       texgen that the r coordinate could be used to select a slice in the
+       3D texture.
+
+    3. What about point smoothing?
+
+       When point smoothing is enabled, a triangle fan could be rendered
+       to approximate a circular point.  This could be problematic to
+       define and implement so POINT_SMOOTH is ignored when drawing sprite
+       points.
+
+       Smoothed points can be approximated by using an appropriate texture
+       images, alpha testing and blending.
+
+       POLYGON_SMOOTH does effect the rendering of the quadrilateral, however.
+
+    4. What about sprite rotation?
+
+       There is none.  Sprite points are always rendered as window-aligned
+       squares.  One could define rotated texture images if desired.  A 3D
+       texture and appropriate texture r coordinates could be used to
+       effectively specify image rotation per point.
+
+    5. What about POLYGON_MODE?
+
+       POLYGON_MODE does not effect the rasterization of the quadrilateral.
+
+    6. What about POLYGON_CULL?
+
+       TBD.  Polygon culling is normally specified and implemented in the
+       transformation stage of OpenGL.  However, some rasterization hardware
+       implements it later during triangle setup.
+
+       Polygon culling wouldn't be useful for sprite points since the
+       quadrilaterals are always defined in counter-clockwise order in
+       window space.  For that reason, polygon culling should probably be
+       ignored.
+
+    7. Should sprite points be alpha-attenuated if their size is below the
+       point parameter's threshold size?
+
+    8. Should there be an advertisized maximum sprite point size?
+
+       No.  Since we're rendering the point as a quadrilateral there's no
+       need to limit the size.

+    Section ???.
+
+    When SPRITE_POINT_MESA is enabled points are rasterized as screen-
+    aligned quadrilaterals.  If the four vertices of the quadrilateral
+    are labeled A, B, C, and D, starting at the lower-left corner and moving
+    counter-clockwise around the quadrilateral, then the vertex and
+    texture coordinates are computed as follows:
+
+      vertex   window coordinate       texture coordinate
+        A      (x-r, y-r, z, w)          (0, 0, r, q)
+        B      (x+r, y-r, z, w)          (1, 0, r, q)
+        C      (x+r, y+r, z, w)          (1, 1, r, q)
+        D      (x-r, y+r, z, w)          (0, 1, r, q)
+
+    where x, y, z, w are the point's window coordinates, r and q are the
+    point's 3rd and 4th texture coordinates  and r is half the point's
+    size.  The other vertex attributes (such as the color and fog coordinate)
+    are simply duplicated from the original point vertex.
+
+    Point size may either be specified with PointSize or computed
+    according to the EXT_point_parameters extension.
+
+    The new texture coordinates are not effected by texgen or the texture
+    matrix.  Note, however, that the texture r and q coordinates are passed
+    unchanged and may have been computed with texgen and/or the texture
+    matrix.
+
+    If multiple texture units are present the same texture coordinate is
+    used for all texture units.
+
+    The point is then rendered as if it were a quadrilateral using the
+    normal point sampling rules.  POLYGON_MODE does not effect the
+    rasterization of the quadrilateral but POLYGON_SMOOTH does.
+
+    POINT_SMOOTH has no effect when SPRITE_POINT_MESA is enabled.

+
+    OpenGL 1.2 is required.
+    The extension is written against the OpenGL 1.2 Specification
+
+Overview
+
+    Provides the application with means to enable and disable logging
+    of GL calls including parameters as readable text. The verbosity
+    of the generated log can be controlled. The resulting logs are
+    valid (but possibly incomplete) C code and can be compiled and 
+    linked for standalone test programs. The set of calls and the 
+    amount of static data that is logged can be controlled at runtime. 
+    The application can add comments and enable or disable tracing of GL 
+    operations at any time. The data flow from the application to GL
+    and back is unaffected except for timing.
+
+    Application-side implementation of these features raises namespace
+    and linkage issues. In the driver dispatch table a simple
+    "chain of responsibility" pattern (aka "composable piepline")
+    can be added.
+
+IP Status
+
+    The extension spec is in the public domain.  The current implementation
+    in Mesa is covered by Mesa's XFree86-style copyright by the authors above.
+    This extension is partially inspired by the Quake2 QGL wrapper.
+
+Issues
+
+ 
+    (1) Is this Extension obsolete because it can
+    be implemented as a wrapper DLL?
+
+      RESOLVED: No. While certain operating systems (Win32) provide linkers 
+      that facilitate this kind of solution, other operating systems
+      (Linux) do not support hierarchical linking, so a wrapper solution
+      would result in symbol collisions.
+      Further, IHV's might have builtin support for tracing GL execution 
+      that enjoys privileged access, or that they do not wish to separate
+      the tracing code from their driver code base.
+
+    (2) Should the Trace API explicitely support the notion of "frames? 
+    This would require hooking into glXSwapBuffers calls as well.
+
+      RESOLVED: No. The application can use NewTraceMESA/EndTraceMESA
+      and TraceComment along with external parsing tools to split the 
+      trace into frames, in whatever way considered adequate.
+
+    (2a) Should GLX calls be traced?
+
+      PBuffers and other render-to-texture solutions demonstrate that
+      context level commands beyond SwapBuffers might have to be
+      traced. The GL DLL exports the entry points, so this would not
+      be out of the question. 
+
+    (3) Should the specification mandate the actual output format?
+
+      RESOLVED: No. It is sufficient to guarantee that all data and commands 
+      will be traced as requested by Enable/DisableTraceMESA, in the order
+      encountered. Whether the resulting trace is available as a readable 
+      text file, binary metafile, compilable source code, much less which 
+      indentation and formatting has been used, is up to the implementation. 
+      For the same reason this specification does not enforce or prohibit
+      additional information added to the trace (statistics, profiling/timing, 
+      warnings on possible error conditions).
+
+    (4) Should the comment strings associated with names and pointer (ranges) 
+    be considered persistent state?
+
+      RESOLVED: No. The implementation is not forced to use this information 
+      on subsequent occurences of name/pointer, and is free to consider it 
+      transient state.
+ 
+    (5) Should comment commands be prohibited between Begin/End?
+
+      RESOLVED: Yes, with the exception of TraceCommentMESA. TraceCommentMESA 
+      is transient, the other commands might cause storage of persistent
+      data in the context. There is no need to have the ability mark names 
+      or pointers between Begin and End.

+
+Additions to Chapter 5 of the OpenGL 1.2.1 Specification (Special Functions)
+
+    Add a new section:
+
+    5.7 Tracing
+
+    The tracing facility is used to record the execution of a GL program
+    to a human-readable log.  The log appears as a sequence of GL commands
+    using C syntax.  The primary intention of tracing is to aid in program
+    debugging.
+
+    A trace is started with the command
+
+      void NewTraceMESA( bitfield mask, const GLubyte * traceName )
+
+    <mask> may be any value accepted by PushAttrib and specifies a set of
+    attribute groups.  The state values included in those attribute groups
+    is written to the trace as a sequence of GL commands.
+
+    <traceName> specifies a name or label for the trace.  It is expected
+    that <traceName> will be interpreted as a filename in most implementations.
+
+    A trace is ended by calling the command
+
+      void EndTraceMESA( void )
+
+    It is illegal to call NewTraceMESA or EndTraceMESA between Begin and End. 
+
+    The commands
+
+      void EnableTraceMESA( bitfield mask )
+      void DisableTraceMESA( bitfield mask )
+
+    enable or disable tracing of different classes of GL commands.
+    <mask> may be the union of any of TRACE_OPERATIONS_BIT_MESA,
+    TRACE_PRIMITIVES_BIT_MESA, TRACE_ARRAYS_BIT_MESA, TRACE_TEXTURES_BIT_MESA,
+    and TRACE_PIXELS_BIT_MESA.  The special token TRACE_ALL_BITS_MESA
+    indicates all classes of commands are to be logged.
+
+    TRACE_OPERATIONS_BIT_MESA controls logging of all commands outside of
+    Begin/End, including Begin/End.
+  
+    TRACE_PRIMITIVES_BIT_MESA controls logging of all commands inside of
+    Begin/End, including Begin/End.
+ 
+    TRACE_ARRAYS_BIT_MESA controls logging of VertexPointer, NormalPointer,
+    ColorPointer, IndexPointer, TexCoordPointer and EdgeFlagPointer commands.
+
+    TRACE_TEXTURES_BIT_MESA controls logging of texture data dereferenced by
+    TexImage1D, TexImage2D, TexImage3D, TexSubImage1D, TexSubImage2D, and
+    TexSubImage3D commands.
+
+    TRACE_PIXELS_BIT_MESA controls logging of image data dereferenced by
+    Bitmap and DrawPixels commands.
+
+    TRACE_ERRORS_BIT_MESA controls logging of all errors. If this bit is 
+    set, GetError will be executed whereever applicable, and the result will 
+    be added to the trace as a comment. The error returns are cached and 
+    returned to the application on its GetError calls. If the user does not 
+    wish the additional GetError calls to be performed, this bit should not
+    be set.
+    
+    The command
+
+      void TraceCommentMESA( const ubyte* comment )
+
+    immediately adds the <comment> string to the trace output, surrounded
+    by C-style comment delimiters.
+
+    The commands
+
+      void TraceTextureMESA( uint name, const ubyte* comment )
+      void TraceListMESA( uint name, const ubyte* comment )
+
+    associates <comment> with the texture object or display list specified
+    by <name>.  Logged commands which reference the named texture object or
+    display list will be annotated with <comment>.  If IsTexture(name) or
+    IsList(name) fail (respectively) the command is quietly ignored.
+
+    The commands
+
+      void TracePointerMESA( void* pointer, const ubyte* comment )
+
+      void TracePointerRangeMESA( const void* first, 
+                                  const void* last,
+                                  const ubyte* comment ) 
+
+    associate <comment> with the address specified by <pointer> or with
+    a range of addresses specified by <first> through <last>.
+    Any logged commands which reference <pointer> or an address between
+    <first> and <last> will be annotated with <comment>.
+
+    The command
+
+      void TraceAssertAttribMESA( bitfield attribMask )
+
+    will add GL state queries and assertion statements to the log to
+    confirm that the current state at the time TraceAssertAttrib is
+    executed matches the current state when the trace log is executed
+    in the future.
+
+    <attribMask> is any value accepted by PushAttrib and specifies
+    the groups of state variables which are to be asserted.
+
+    The commands NewTraceMESA, EndTraceMESA, EnableTraceMESA, DisableTraceMESA,
+    TraceAssertAttribMESA, TraceCommentMESA, TraceTextureMESA, TraceListMESA, 
+    TracePointerMESA and TracePointerRangeMESA are not compiled into display lists.
+
+
+    Examples:
+
+    The command NewTraceMESA(DEPTH_BUFFER_BIT, "log") will query the state
+    variables DEPTH_TEST, DEPTH_FUNC, DEPTH_WRITEMASK, and DEPTH_CLEAR_VALUE
+    to get the values <test>, <func>, <mask>, and <clear> respectively.
+    Statements equivalent to the following will then be logged:
+
+       glEnable(GL_DEPTH_TEST);   (if <test> is true)
+       glDisable(GL_DEPTH_TEST);  (if <test> is false)
+       glDepthFunc(<func>); 
+       glDepthMask(<mask>);
+       glClearDepth(<clear>);
+   
+
+    The command TraceAssertAttribMESA(DEPTH_BUFFER_BIT) will query the state
+    variables DEPTH_TEST, DEPTH_FUNC, DEPTH_WRITEMASK, and DEPTH_CLEAR_VALUE
+    to get the values <test>, <func>, <mask>, and <clear> respectively.
+    The resulting trace might then look will like this:
+
+    {
+      GLboolean b;
+      GLint i;
+      GLfloat f;
+      b = glIsEnabled(GL_DEPTH_TEST);
+      assert(b == <test>);
+      glGetIntegerv(GL_DEPTH_FUNC, &i);
+      assert(i == <func>);
+      glGetIntegerv(GL_DEPTH_MASK, &i);
+      assert(i == <mask>);
+      glGetFloatv(GL_DEPTH_CLEAR_VALUE, &f);
+      assert(f == <clear>);
+    }
+
+
+Additions to Chapter 6 of the OpenGL 1.2.1 Specification 
+    (State and State Requests)
+
+    Querying TRACE_MASK_MESA with GetIntegerv, GetFloatv, GetBooleanv or
+    GetDoublev returns the current command class trace mask.
+
+    Querying TRACE_NAME_MESA with GetString returns the current trace name.
+
+
+Additions to Appendix A of the OpenGL 1.2.1 Specification (Invariance)
+
+    The MESA_trace extension can be used in a way that does not affect data 
+    flow from application to OpenGL, as well as data flow from OpenGL to 
+    application, except for timing, possible print I/O. TRACE_ERRORS_BIT_MESA
+    will add additional GetError queries. Setting a trace mask with NewTraceMESA
+    as well as use of TraceAssertAttribMESA might cause additional state queries.
+    With the possible exception of performance, OpenGL rendering should not be
+    affected at all by a properly chosen logging operation.
+
+Additions to the AGL/GLX/WGL Specifications
+
+    None.
+
+GLX Protocol
+
+    None. The logging operation is carried out client-side, by exporting
+    entry points to the wrapper functions that execute the logging operation.
+
+Errors
+
+    INVALID_OPERATION is generated if any trace command except TraceCommentMESA
+    is called between Begin and End.
+
+New State
+
+    The current trace name and current command class mask are stored
+    per-context.
+
+New Implementation Dependent State
+
+    None.

+
+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 3.5) designate new developmental releases.
+Even numbered versions (such as 3.4) designate stable releases.
+
+The biggest change in Mesa 3.5 is a complete overhaul of the source
+code in order to make it more modular.  This was driven by the DRI
+hardware drivers.  It simplifies the DRI drivers and opens the door
+to hardware transform/clip/lighting (TCL).  Keith Whitwell can take
+the credit for that.
+
+
+
+Driver Support
+--------------
+
+The device driver interface in Mesa 3.5 has changed a lot since Mesa 3.4
+Not all of the older Mesa drivers have been updated.  Here's the status:
+
+Driver			Status
+----------------------	-----------
+XMesa (Xlib)		updated
+OSMesa (off-screen)	updated
+FX (3dfx Voodoo1/2)	updated
+SVGA			updated
+GGI			not updated
+Windows/Win32		not updated
+DOS/DJGPP		not updated
+BeOS			not updated
+Allegro			not updated
+D3D			not updated
+DOS			not updated
+
+We're looking for volunteers to update the remaining drivers.  Please
+post to the Mesa3d-dev mailing list if you can help.
+
+
+
+GLU 1.3
+-------
+
+Mesa 3.5 includes the SGI Sample Implementation (SI) GLU library.
+This version of GLU supports the GLU 1.3 specification.  The old
+Mesa GLU library implemented the 1.1 specification.  The SI GLU
+library should work much better.
+
+You'll need a C++ compiler to compile the SI GLU library.  This may
+be a problem on some systems.
+
+
+
+New Extensions
+--------------
+
+GL_EXT_convolution
+	Adds image convolution to glRead/Copy/DrawPixels/TexImage.
+
+GL_ARB_imaging
+	This is the optional imaging subset of OpenGL 1.2.
+	It's the GL_EXT_convolution, GL_HP_convolution_border_modes,
+	GL_EXT_histogram, GL_EXT_color_table, GL_EXT_color_subtable
+	GL_EXT_blend_color, GL_EXT_blend_minmax, GL_EXT_blend_subtract
+	and GL_SGI_color_matrix extensions all rolled together.
+	This is supported in all software renderers but not in all
+	hardware drivers (3dfx for example).
+
+GL_ARB_texture_compression
+	This is supported in Mesa but only used by the 3dfx DRI drivers
+	for Voodoo4 and later.
+
+GL_ARB_texture_env_add
+	This is identical to GL_EXT_texture_env_add.
+
+GL_NV_blend_square
+	Adds extra blend source and dest factors which allow squaring
+	of color values.
+
+GL_EXT_fog_coord
+	Allows specification of a per-vertex fog coordinate instead of
+	having fog always computed from the eye distance.
+
+GL_EXT_secondary_color
+	Allows specifying the secondary (specular) color for each vertex
+	instead of getting it only from lighting in GL_SEPARATE_SPECULAR_COLOR
+	mode.
+
+GL_ARB_texture_env_combine
+	Basically the same as GL_EXT_texture_env_combine
+
+GL_ARB_texture_env_add extension
+	Texture addition mode.
+
+GL_ARB_texture_env_dot3 extension
+	Dot product texture environment.
+
+GL_ARB_texture_border_clamp
+	Adds GL_CLAMP_TO_BORDER_ARB texture wrap mode
+
+GL_SGIX_depth_texture, GL_SGIX_shadow and GL_SGIX_shadow_ambient
+	Implements a shadow casting algorithm based on depth map textures
+
+GL_SGIS_generate_mipmap
+	Automatically generate lower mipmap images whenever the base mipmap
+	image is changed with glTexImage, glCopyTexImage, etc.
+
+
+
+libOSMesa.so
+------------
+
+libOSMesa.so is a new library which contains the OSMesa interface for
+off-screen rendering.  Apps which need the OSMesa interface should link
+with both -lOSMesa and -lGL.  This change was made so that stand-alone
+Mesa works the same way as XFree86/DRI's libGL.
+
+
+
+Device Driver Changes / Core Mesa Changes
+-----------------------------------------
+
+The ctx->Driver.LogicOp() function has been removed.  It used to
+be called during state update in order to determine if the driver
+could do glLogicOp() operations, and if not, set the SWLogicOpEnabled
+flag.  Drivers should instead examine the LogicOp state themselves
+and choose specialized point, line, and triangle functions appropriately,
+or fall back to software rendering.  The Xlib driver was the only driver
+to use this function.  And since the Xlib driver no longer draws
+points, lines or triangles using Xlib, the LogicOp function isn't needed.
+
+The ctx->Driver.Dither() function has been removed.  Drivers should
+detect dither enable/disable via ctx->Driver.Enable() instead.
+
+The ctx->Driver.IndexMask() and ctx->Driver.ColorMask() functions
+are now just called from glIndexMask and glColorMask like the other
+GL state-changing functions.  They are no longer called from inside
+gl_update_state().  Also, they now return void.  The change was made
+mostly for sake of uniformity.
+
+The NEW_DRVSTATE[0123] flags have been removed.  They weren't being used
+and are obsolete w.r.t. the way state updates are done in DRI drivers.
+
+
+Removed obsolete gl_create_visual() and gl_destroy_visual().
+
+Renamed functions (new namespace):
+
+old				new
+gl_create_framebuffer		_mesa_create_framebuffer
+gl_destroy_framebuffer		_mesa_destroy_framebuffer
+gl_create_context		_mesa_create_context
+gl_destroy_context		_mesa_destroy_context
+gl_context_initialize		_mesa_context_initialize
+gl_copy_context			_mesa_copy_context
+gl_make_current			_mesa_make_current
+gl_make_current2		_mesa_make_current2
+gl_get_current_context		_mesa_get_current_context
+gl_flush_vb			_mesa_flush_vb
+gl_warning			_mesa_warning
+gl_compile_error		_mesa_compile_error
+
+
+All the drivers have been updated, but not all of them have been
+tested since I can't test some platforms (DOS, Windows, Allegro, etc).
+
+
+X/Mesa Driver
+-------------
+
+The source files for the X/Mesa driver in src/X have been renamed.
+The xmesa[1234].c files are gone.  The new files are xm_api.c,
+xm_dd.c, xm_line.c, xm_span.c and xm_tri.c.
+
+
+
+Multitexture
+------------
+
+Eight texture units are now supported by default.
+
+
+
+OpenGL SI related changes
+-------------------------
+
+In an effort to make Mesa's internal interfaces more like the OpenGL
+SI interfaces, a number of changes have been made:
+
+1. Importing the SI's glcore.h file which defines a number of
+interface structures like __GLimports and __GLexports.
+
+2. Renamed "struct gl_context" to "struct __GLcontextRec".
+
+3. Added __glCoreCreateContext() and __glCoreNopDispatch() functions.
+
+4. The GLcontext member Visual is no longer a pointer.
+
+5. New file: imports.c to setup default import functions for Mesa.
+
+
+
+
+16-bit color channels
+---------------------
+
+There's experimental support for 16-bit color channels (64-bit pixels)
+in Mesa 3.5.  Only the OSMesa interface can be used for 16-bit rendering.
+Type "make linux-osmesa16" in the top-level directory to build the
+special libOSMesa16.so library.
+
+This hasn't been tested very thoroughly yet so please file bug reports
+if you have trouble.
+
+In the future I hope to implement support for 32-bit, floating point
+color channels.
