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
-----------------------------------------
@@ -75,5 +85,64 @@ 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):

gl_create_framebuffer _mesa_create_framebuffer
gl_destroy_framebuffer _mesa_destroy_framebuffer
gl_create_context _mesa_create_context

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).
Multitexture
------------
Three texture units are now supported by default. We'll allow more
than three texture units when we fix some bitfield issues. In at least
one place we have a 32-bit bitfield which is fully allocated, leaving
no space for texture unit #3 or higher.
The TEXTURE1_1D, TEXTURE1_2D, etc constants may go away in the future.
Currently, they're only used in the ctx->Texture.ReallyEnabled field.
This bitfield is just a conglomerate of ctx->Texture.Unit[i].ReallyEnabled
for all <i> texture units. ctx->Texture.ReallyEnabled may become a
GLboolean. Then, drivers will have to loop over the texture units to
examine ctx->Texture.Unit[i].ReallyEnabled.
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.
