-Introduction
-------------
-
-This document describes the implementation of the XFree86 4.0 libGL.so
-library defined by the Linux/OpenGL Base specification found at
-http://reality.sgi.com/opengl/linux/linuxbase.html.
-
-The documentation is divided into two sections:
-    User's Guide
-    Driver Developer's Guide
-
-Author:  Brian Paul     (brian@precisioninsight.com)
-Date:    February 2000
-
-
-
-User's Guide
-------------
-
-Using libGL.so
-
-The libGL.so library defines the gl- and glX-prefixed functions needed to
-run OpenGL programs.  OpenGL client applications should link with the
--lGL option to use it.
-
-libGL.so serves two primary functions: GLX protocol generation for indirect
-rendering and loading/management of hardware drivers for direct rendering.
-
-When libGL.so initializes itself it uses the DRI to determine the
-appropriate hardware driver for each screen on the local X display.
-The hardware drivers are expected to be in the /usr/X11R6/lib/modules/dri/
-directory.  Drivers are named with the convention <name>_dri.so where
-<name> is a driver such as "tdfx", "i810", "gamma", etc.
-
-The LIBGL_DRIVERS_DIR environment variable may be used to specify a
-different DRI modules directory, overriding /usr/X11R6/lib/modules/dri/.
-This environment variable is ignored in setuid programs for security
-reasons.
-
-When libGL.so is unable to locate appropriate hardware drivers it will
-fall back to using indirect GLX rendering.
-
-To aid in solving problems, libGL.so will print diagnostic messages to
-stderr if the LIBGL_DEBUG environment variable is defined.
-
-libGL.so is thread safe.  The overhead of thread safety for common,
-single-thread clients is negligible.  However, the overhead of thread
-safety for multi-threaded clients is significant.  Each GL API call
-requires two calls to pthread_get_specific() which can noticably
-impact performance.  Warning:  libGL.so is thread safe but individual
-DRI drivers may not be.  Please consult the documentation for a driver
-to learn if it is thread safe.
-
-
-
-Indirect Rendering
-
-You can force indirect rendering mode by setting the LIBGL_ALWAYS_INDIRECT
-environment variable.  Hardware acceleration will not be used.
-
-
-
-libGL.so Extensibility
-
-libGL.so is designed to be extended without upgrading.  That is,
-drivers may install new OpenGL extension functions into libGL.so
-without requiring libGL.so to be replaced.  Clients of libGL.so should
-use the glXGetProcAddressEXT() function to obtain the address of
-functions by name.  For more details of GLX_ARB_get_proc_address see
-http://oss.sgi.com/projects/ogl-sample/registry/ARB/get_proc_address.spec
-
-libGL.so is also designed with flexibility such that it may be used
-with many generations of hardware drivers to come.
-
-
-
-
-Driver Developer's Guide
-------------------------
-
-This section describes the requirements to make an XFree86 4.0
-libGL.so-compatible hardware driver.  It is not intended for end
-users of libGL.so.
-
-
-XFree86 source files
-
-libGL.so is built inside XFree86 with sources found in xc/lib/GL/.
-Specifically, libGL.so is built from:
-
-	xc/lib/GL/glx/*.c
-	xc/lib/dri/XF86dri.c
-	xc/lib/dri/dri_glx.c
-	xc/lib/GL/mesa/src/glapi.c
-	xc/lib/GL/mesa/src/glapitemp.h
-	xc/lib/GL/mesa/src/glapitable.h
-	xc/lib/GL/mesa/src/glapioffsets.h
-	xc/lib/GL/mesa/src/glapinoop.c
-	xc/lib/GL/mesa/src/glheader.h
-	xc/lib/GL/mesa/src/glthread.c
-	xc/lib/GL/mesa/src/glthread.h
-	xc/lib/GL/mesa/src/X86/glapi_x86.S
-	xc/lib/GL/mesa/src/X86/assyntax.h
-
-Understand that the mesa/src/gl*.[ch] files are not tied to Mesa.  They
-have no dependencies on the rest of Mesa and are designed to be reusable
-in a number of projects.
-
-The glapi_x86.X and assyntax.h files implement x86-optimized dispatch
-of GL functions.  They are not required; C-based dispatch can be used
-instead, with a slight performance penalty.
-
-
-
-Driver loading and binding
-
-When libGL.so initializes itself (via the __glXInitialize function) a
-call is made to driCreateDisplay().  This function uses DRI facilities
-to determine the driver file appropriate for each screen on the local
-display.  Each screen's driver is then opened with dlopen() and asked
-for its __driCreateScreen() function.  The pointers to the __driCreateScreen()
-functions are kept in an array, indexed by screen number, in the
-__DRIdisplayRec struct.
-
-When a driver's __driCreateScreen() function is called, it must initialize
-a __DRIscreenRec struct.  This struct acts as the root of a tree of
-function pointers which are called to create and destroy contexts and
-drawables and perform all the operations needed by the GLX interface.
-See the xc/lib/GL/glx/glxclient.h file for details.
-
-
-
-Dynamic Extension Function Registration
-
-In order to provide forward compatibility with future drivers, libGL.so
-allows drivers to register new OpenGL extension functions which weren't
-known when libGL.so was built.
-
-The register_extensions() function in xc/lib/GL/dri/dri_glx.c is called
-as soon as libGL.so is loaded.  This is done with gcc's constructor
-attribute.  This mechanism will likely have to be changed for other compilers.
-
-register_extensions() loops over all local displays and screens, determines
-the DRI driver for each, and calls the driver's __driRegisterExtensions()
-function, if present.
-
-The __driRegisterExtensions() function can add new entrypoints to libGL
-by calling:
-
-    GLboolean _glapi_add_entrypoint(const char *funcName, GLuint offset)
-
-The parameters are the name of the function (such as "glFoobarEXT") and the
-offset of the dispatch slot in the API dispatch table.  The return value
-indicates success (GL_TRUE) or failure (GL_FALSE).
-
-_glapi_add_entrypoint() will synthesize entrypoint code in assembly
-language.  Assembly languages is required since parameter passing
-can't be handled correctly using a C-based solution.
-
-The address of the new entrypoint is obtained by calling the
-glXGetProcAddressARB() function.
-
-The dispatch offset number MUST be a number allocated by SGI in the same
-manner in which new GL_* constants are allocated.  Using an arbitrary
-offset number will result in many problems.
-
-
-
-Dispatch Management
-
-When a GL context is made current, the driver must install its dispatch
-table as the current dispatch table.  This is done by calling
-
-	void _glapi_set_dispatch(struct _glapi_table *dispatch);
-
-This will install the named dispatch table for the calling thread.
-The current dispatch table for a thread can be obtained by calling
-
-	struct _glapi_table *_glapi_get_dispatch(void);
-
-For higher performance in the common single-thread case, the global
-variable _glapi_Dispatch will point to the current dispatch table.
-This variable will be NULL when in multi-thread mode.
-
-
-
-Context Management
-
-libGL.so uses the XFree86 xthreads package to manage a thread-specific
-current context pointer.  See __glXGet/SetCurrentContext() in glext.c
-
-Drivers may use the _glapi_set/get_context() functions to maintain
-a private thread-specific context pointer.
