-Overview
-
-    Since Mesa allows RGB rendering into drawables with PseudoColor,

-    in order to compute pixel values during rendering.
-
-    The colormap associated with a window can be queried with normal
-    Xlib functions but there is no colormap associated with pixmaps.
-
-    The glXCreateGLXPixmapMESA function is an alternative to glXCreateGLXPixmap
-    which allows specification of a colormap.

-
-    The Mesa implementation of GLX allows RGB rendering into X windows and
-    pixmaps of any visual class, not just TrueColor or DirectColor.  In order
-    to compute pixel values from RGB values Mesa requires a colormap.
-
-    The function
-
-	GLXPixmap glXCreateGLXPixmapMESA( Display *dpy, XVisualInfo *visual,
-					  Pixmap pixmap, Colormap cmap );
-
-    allows one to create a GLXPixmap with a specific colormap.  The image
-    rendered into the pixmap may then be copied to a window (which uses the
-    same colormap and visual) with the expected results.

-    Mesa's implementation of GLX is entirely implemented on the client side.

-    or pixmap.
-
-    The glxMesaReleaseBuffers() function can be used to explicitly indicate
-    when the back color buffer, depth buffer, stencil buffer, and/or accum-
-    ulation buffer associated with a drawable can be freed.

 Mesa Threads README
 -------------------
 
-Thread safety was introduced in Mesa 2.6 by John Stone and
-Christoph Poliwoda.
-
-It was redesigned in Mesa 3.3 so that thread safety is
-supported by default (on systems which support threads,
-that is).  There is no measurable penalty on single
-threaded applications.
-
-NOTE that the only _driver_ which is thread safe at this time
-is the OS/Mesa driver!
-
-
-At present the mthreads code supports three thread APIS:
+Mesa 2.6 is the starting point for an effort to make Mesa 
+safe in multithreaded applications.  The files src/mthreads.c and
+src/mthreads.h provide a platform independent threads API which Mesa
+uses internally to provide thread-safe operation.  At present the mthreads
+code supports three thread APIS:
   1) POSIX threads (aka pthreads).
   2) Solaris / Unix International threads.
   3) Win32 threads (Win 95/NT).
 
-Support for other thread libraries can be added src/glthread.[ch]
+Here's the current list of targets which enable multithreaded handling
+in Mesa:
 
+  linux-386-pthread    for Linux w/ Intel assembly and linuxthreads
+  sunos5-thread        for Suns with SunOS 5.x, using Solaris threads

-In order to guarantee proper operation, it is
+In order to use Mesa with a multithreaded application, Mesa must be compiled
+using one of the thread-enabled configurations.  In cases where a platform
+supports multiple APIs which are acceptable to Mesa, Mesa must be built
+with the same threads API as the application in order for things to work
+properly.  For example, Solaris >= 2.5 support both POSIX threads and
+Sun's own threads API.  In order to guarantee proper operation, it is
 necessary for both Mesa and application code to use the same threads API.
 So, if your application uses Sun's thread API, then you should build Mesa
 using one of the targets for Sun threads.
 
+Since this effort is still very much a work in progress, not all 
+aspects of Mesa are thread safe.  As of this release (Mesa 2.6) only the
+osmesa drivers have been made MT-safe.  As work continues, other drivers
+such as the X11 drivers will also incorporate MT-safe features.

 The mtdemos directory contains some example programs which use 
 multiple threads to render to osmesa rendering context(s).

-
-Introduction
-------------
-
-Mesa uses an even/odd version number scheme like the Linux kernel.
-Odd numbered versions (such as 3.3) designate new developmental releases.
-Even numbered versions (such as 3.2.1) designate stable releases.
-
-Mesa 3.3 has a undergone many internal changes since version 3.2
-and features a lot of new extensions.  3.3 is expected to be pretty
-stable, but perhaps not as stable as 3.2 which has been used by
-thousands of users over the past months.
-
-Everyone is encouraged to try Mesa 3.3.  Bugs should be reported to
-the Mesa bug database on www.sourceforge.net.
-
-
-
-Header file / GLenum changes
-----------------------------
-
-The gl.h and glu.h headers now use #defines to define all GL_* tokens
-instead of C-language enums.  This change improves Mesa/OpenGL
-interoperability.
-
-
-
-New API dispatch code
----------------------
-
-The core Mesa gl* functions are now implemented with a new dispatch
-(jump table) which will allow simultaneous direct/indirect rendering.
-
-The code is found in the glapi*.[ch] files.
-
-Of interest:  the actual "glFooBar" functions are generated with
-templatized code defined in glapitemp.h and included by glapi.c
-The glapitemp.h template should be reusable for all sorts of OpenGL
-projects.
-
-The new dispatch code has also optimized with x86 assembly code.
-This optimization eliminates copying the function arguments during
-dispatch.
-
-
-
-New thread support
-------------------
-
-Thread support in Mesa has been rewritten.  The glthread.[ch] files
-replace mthreads.[ch].  Thread safety is always enabled (on platforms
-which support threads, that is).  There is virtually no performance
-penalty for typical single-thread applications.  See the glapi.c
-file for details.
-
-The Xlib driver (XMesa) is now thread-safe as well.  Be sure to
-call XInitThreads() in your app first.  See the xdemos/glthreads.c
-demo for an example.
-
-
-
-Make configuration changes
---------------------------
-
-If you use the old-style (non GNU automake) method to build Mesa note
-that several of the configuration names have changed:
-
-   Old name        New name
-   -------------   ----------------
-   linux-elf       linux
-   linux           linux-static
-   linux-386-elf   linux-386
-   linux-386       linux-386-static
-   etc.
-
-
-
-New extensions
---------------
-
-GL_ARB_transpose_matrix
-	Adds glLoadTransposeMatrixARB() and glMultTransposeMatrixARB()
-        functions.
-
-GL_ARB_texture_cube_map
-	For cube-based reflection mapping.
-
-GL_EXT_texture_add_env
-	Adds GL_ADD texture environment mode.
-	See http://www.berkelium.com/OpenGL/EXT/texture_env_add.txt
-
-GL_EXT_texture_lod_bias
-	Allows mipmapped texture blurring and sharpening.
-
-GLX_EXT_visual_rating extension
-	This extension has no effect in stand-alone Mesa (used for DRI).
-
-GL_HP_occlusion_test
-	Used for bounding box occlusion testing (see demos/occlude.c).
-
-GL_SGIX_pixel_texture / GL_SGIS_pixel_texture
-	Lets glDraw/CopyPixels draw a texture coordinate image.
-
-GL_SGI_color_matrix
-	Adds a color matrix and another set of scale and bias parameters
-	to the glDraw/CopyPixels paths.
-
-GL_SGI_color_table
-	Adds additional color tables to the glDraw/Read/CopyPixels paths.
-
-GL_EXT_histogram
-	Compute histograms for glDraw/Read/CopyPixels.
-
-GL_EXT_blend_func_separate
-	This is the same as GL_INGR_blend_func_separate.
-
-GL_ARB_texture_cube_mapping
-	6-face cube mapping, nicer than sphere mapping
-
-GL_EXT_texture_env_combine
-	For advanced texture environment effects.
-
-
-Documentation for all these functions can be found at
-http://oss.sgi.com/projects/ogl-sample/registry/
-
-
-
-GLX_SGI_make_current_read functionality
----------------------------------------
-
-The functionality of this extension is needed for GLX 1.3 (and required
-for the Linux/OpenGL standards base).
-
-Implementing this function required a **DEVICE DRIVER CHANGE**.
-The old SetBuffer() function has been replaced by SetReadBuffer() and
-SetDrawBuffer().  All device drivers will have to be updated because
-of this change.
-
-The new function, glXMakeContextCurrent(), in GLX 1.3 now works in Mesa.
-The xdemos/wincopy.c program demonstrates it.
-
-
-
-Image-related code changes
---------------------------
-
-The imaging path code used by glDrawPixels, glTexImage[123]D,
-glTexSubImage[123], etc has been rewritten.  It's now faster,
-uses less memory and has several bug fixes.  This work was
-actually started in Mesa 3.1 with the glTexImage paths but has now
-been carried over to glDrawPixels as well.
-
-
-
-Device driver interface changes
--------------------------------
-
-Added new functions for hardware stencil buffer support:
-   WriteStencilSpan
-   ReadStencilSpan
-   WriteStencilPixels
-   ReadStencilPixels
-
-
-Removed old depth buffer functions:
-   AllocDepthBuffer
-   DepthTestSpan
-   DepthTestPixels
-   ReadDepthSpanFloat
-   ReadDepthSpanInt
-
-
-Added new depth buffer functions:
-   WriteDepthSpan
-   ReadDepthSpan
-   WriteDepthPixels
-   ReadDepthPixels
-
-   These functions always read/write 32-bit GLuints.  This will allow
-   drivers to have anywhere from 0 to 32-bit Z buffers without
-   recompiling for 16 vs 32 bits as was previously needed.
-
-
-New texture image functions
-   The entire interface for texture image specification has been updated.
-   With the new functions, it's optional for Mesa to keep an internal copy
-   of all textures.  Texture download should be a lot faster when the extra
-   copy isn't made.
-
-Misc changes
-   TexEnv now takes a target argument
-   Removed UseGlobalTexturePalette (use Enable function instead)
-
-
-Also added
-   ReadPixels
-   CopyPixels
-
-
-The SetBufffer function has been replaced by SetDrawBuffer and
-SetReadBuffer functions.  This lets core Mesa independently
-specify which buffer is to be used for reading and which for
-drawing.
-
-The Clear function's mask parameter has changed.  Instead of
-mask being the flags specified by the user to glClear, the
-mask is now a bitmask of the DD_*_BIT flags in dd.h.  Now
-multiple color buffers can be specified for clearing (ala
-glDrawBuffers).  The driver's Clear function must also
-check the glColorMask glIndexMask, and glStencilMask settings
-and do the right thing.  See the X/Mesa, OS/Mesa, or FX/Mesa
-drivers for examples.
-
-
-The depth buffer changes shouldn't be hard to make for existing
-drivers.  In fact, it should simply the code.  Be careful with
-the depthBits value passed to gl_create_context().  1 is a bad
-value!  It should normally be 0, 16, 24, or 32.
-
-
-gl_create_framebuffer() takes new arguments which explicitly tell
-core Mesa which ancillary buffers (depth, stencil, accum, alpha)
-should be implemented in software.  Mesa hardware drivers should
-carefully set these flags depending on which buffers are in the
-graphics card.
-
-
-
-Internal constants
-------------------
-
-Point and line size range and granularity limits are now stored
-in the gl_constants struct, which is the Const member of GLcontext.
-The limits are initialized from values in config.h but may be
-overridden by device drivers to reflect the limits of that driver's
-hardware.
-
-Also added constants for NumAuxBuffers and SubPixelBits.
-
-
-
-OpenGL Conformance
-------------------
-
-Mesa now passes all the OpenGL 1.1 conformance tests, except for
-antialiased lines.  AA lines fail on some, but not all, the tests.
-In order to fix the remaining failures, a new AA line algorithm will
-be needed (which computes coverage values for end-point fragments).
-This will be done for Mesa 3.5/3.6.
-
-
-
-OpenGL 1.2 GL_ARB_imaging subset
---------------------------------
-
-Mesa 3.3 implements all the features of GL_ARB_imaging except for
-image convolution.  This will (hopefully) be done for Mesa 3.5/3.6.

-

-INTRODUCTION
-------------
-
-This directory is usually included in the Mesa demos distribution or
-in the GLUT distribution.
-
-I have written the demos included in this directory mainly for showing
-the capabilities of the Mesa library when using the Voodoo driver.
-However all the demos are written using the GLUT and OpenGL so they
-work with any GLUT/OpenGL platform (tested: Linux+Mesa+Voodoo driver,
-Linux+Mesa+X11 driver, Win95+Mesa+Voodoo driver and SGI Onyx IR thanks
-to Mark Kilgard).
-
-All the demos make an heavy use of texture mapping, blending, etc. so
-you _need_ some kind of hardware support for the OpenGL otherwise they
-will run at ~1fps. You need also a OpenGL 1.1 compliant library.
-
-You can find some screenshot of these demos at
-http://www-hmw.caribel.pisa.it/fxmesa/fxdemos.hmtl
-
-Write me if you find some bug in the demos.

-A BRIEF DESCRIPTION OF THE DEMOS
---------------------------------
-
-
-IPERS
------
-
-Sources: ipers.c image.c
-
-A nice spinning fractal object.
-
-
-RAY
----
-
-Sources: ray.c
-
-I'm using ray tracing to dynamically generate texture maps with
-specular, diffuse, shadows, and mirror colors. Each frame the texture
-maps of the plane and of the sphere are partially updated.  With this
-technique you can obtain true mirrors, shadows, specular highlights,
-bump mapping, etc. in realtime.  This demo is really CPU intensive
-(~25fps on a PentiumII@300MHz with a Pure3D).  Support on-the-fly
-switching between fullscreen and in-window rendering under Linux/Mesa
-(start your X server in 16 bpp mode and press the spacebar).
-
-
-TUNNEL
-------
-
-Sources: tunnel.c image.c sources.c
-Data: bw.rgb tile.rgb
-
-The model was designed and prelighted with Alias|Wavefront
-PowerAnimator V8. Triangle strips were built with a tool written by me
-and then statically included in the sources.  This demo doesn't
-require the ZBuffer and use antialiased polygons.  Support on-the-fly
-switching between fullscreen and in-window rendering under Linux/Mesa
-(start your X server in 16 bpp mode and press the spacebar).
-
-
-TUNNEL2
-------
-
-Sources: tunnel2.c image.c sources.c
-Data: bw.rgb tile.rgb
-
-The some tunnel demo but with two output channels. A nice
-example of the Mesa/Voodoo support for multiple boards in
-the some PC.
-
-
-TEAPOT
-------
-
-Sources: teapot.c image.c dteapot.c shadow.c
-Data: bw.rgb tile.rgb
-
-The shadow is drawn projecting the teapot geometry over the plane. All
-other light effects are drawn using the standard OpenGL capabilities.
-Support on-the-fly switching between fullscreen and in-window
-rendering under Linux/Mesa (start your X server in 16 bpp mode and
-press the spacebar).
-
-
-FIRE
-----
-
-Sources: fire.c image.c
-Data: s128.rgb tree2.rgb
-
-The demo use a small particle system to draw some nice visual effect.
-You can interactively change many parameters of the particle system
-and you can choose the number of particles at the startup ('fire
-4000').  This demo should be called fountain.  Support on-the-fly
-switching between fullscreen and in-window rendering under Linux/Mesa
-(start your X server in 16 bpp mode and press the spacebar).
-
-
-TERRAIN
--------
-
-Sources: mesaland.c
-
-This demo is base on another demo written by Mikael SkiZoWalker.  I
-have added the capabilities to freely fly around, view culling and
-some nice color.  Support on-the-fly switching between fullscreen and
-in-window rendering under Linux/Mesa (start your X server in 16 bpp
-mode and press the spacebar).
-
-
-GLTEST
-------
-
-Sources: gltest.c
-
-This is a simple benchmark suite that I'm using in the development of
-the Mesa/Voodoo driver. Type 'gltest >my.res' and you will get some
-data about the performances of your OpenGL. Follow the results with my
-PC (Linux+Mesa-2.6+PentiumII@300MHz+Pure3D):

- * How this works:
- * 1. We load the image into a 2D texture.
- * 2. We generate a sequence of RGB images in which the R component
- *    is really the S texture coordinate and the G component is really
- *    the T texture coordinate.
- *    By warping the mapping from R to S and G to T we can get non-linear
- *    distortions.
- * 3. Draw the warped image (a 2-D warping function) with pixel texgen
- *    enabled.
- * 4. Loop over the warped images to animate.
- *
- * The pixel texgen extension can also be used to do color-space
- * conversions.  For example, we could convert YCR to RGB with a
- * 3D texture map which takes YCR as the S,T,R texture coordinate and
- * returns RGB texel values.
- *
- * You can use this extension in (at least) two ways:
- * 1. glDrawPixels w/ color space conversion/warping
- * 2. glDrawPixels to spatially warp another image in texture memory
- *
- * We're basically using glDrawPixels to draw a texture coordinate image.
