Add some comments to i810ChooseTextureFormat.  There's some strangeness with
i810 texture formats.

primarilly needed to support functions that are internally implemented using
extension entry points (e.g., glBlendFunc uses glBlendFuncSeparate).

This can happen when all the texture enables for a texture unit are disabled.

This fixes bugzilla #3195.

The GL_RENDERER string now accurately contains the chip name.  This was only
tested on a "plain" i810 (PCI ID 8086:7121).

for better performance. (Roland Scheidegger)

In _mesa_TexEnvfv, do not accept values for GL_OPERAND2_ALPHA and GL_OPERAND2_RGB which are only valid with ARB_texture_env_combine but not with EXT_texture_env_combine, when only EXT_texture_env_combine is supported.

Make 'USING_EGL=0' the default for now.  It's causing too much confusion for
too many non-developers (which in turn wastes too much developer time).  It
is trivially overridden from the make command line.  See comments in
linux-dri.

Add additional checks for the *DRIRec info structure passed in from the
device driver. This ensures that things fallback to indirect rendering if
the DDX driver has had modifications (i.e. removal of the drmAddress field).

structure to the 3D drivers view of it, and abort if they don't match.

This traps the case with the drmAddress removal in the DDX driver.

extension wasn't enabled.  I have verified its correct function with Mesa's
stencil_wrap test.  It is enabled on both Savage4 and Savage3D.  Since
Savage3D uses a software fallback for *all* stencil operations, this is safe.

should be defined.  It was flawed on some platforms (e.g., Darwin & mingw).
Instead, rely on the build system to define it on the compiler command line.

This also reverts ajax's hand-edit to indirect_size.c.  I'll fix that on the
X.org side of things later today.

proper DRM_CAS_RESULT to declare the variable used to store the result
of DRM_CAS.  Second, only use the "real" versions of LOCK_HARDWARE and
UNLOCK_HARDWARE on SPARC.  That's the only platform where the hardware

the driver.  The loader now takes care of this for the driver.

Remove _glapi_DispatchTSD and give _glapi_Dispatch its semantic (i.e.,
having a NULL value means that the application is multithreaded and
_glapi_get_dispatch must be called).

Gut all of the dispatch override code.  This removes _glapi_RealDispatch,
_glapi_tls_RealDispatch, _glapi_begin_dispatch_override,
_glapi_end_dispatch_override, and _glapi_get_override_dispatch.

Remove _glapi_get_proc_address, _glapi_get_proc_name, _glapi_get_version,
and _glapi_check_table from the loader / driver interface.

GL_NV_vertex_program, it will explode.  This patch adds GL_NV_vertex_program
to the list of default extensions whose entry points are added by
driInitExtensions.

Thanks go to Roland Scheidegger for tracking the problem down and suggesting
the fix.
