Mesa has never any portion of this extension, and neither has any
other vendor.

The year 2006 apparently came from the "Last Modified Date" in the
spec header. however, the revision history at the bottom say "2/22/00
mjk - added NVIDIA Implementation Details." From that we can safely
infer that the spec is from at least 2000, and it may even be older.

The following extensions are always enabled, and drivers do not have
to option to disable them:
GL_ARB_multisample
GL_ARB_texture_compression
GL_ARB_vertex_buffer_object / GL_OES_mapbuffer
GL_EXT_copy_texture
GL_EXT_multi_draw_arrays / GL_SUN_multi_draw_arrays
GL_EXT_polygon_offset
GL_EXT_subtexture
GL_EXT_texture_edge_clamp / GL_SGIS_texture_edge_clamp
GL_EXT_vertex_array
GL_SGIS_generate_mipmap
This set was picked because the are all either required or optional
features in desktop OpenGL, OpenGL ES 1.x, and OpenGL ES 2.x. The
existing support for some is already partially broken in Mesa (e.g.,
proxy texture targets in OpenGL ES). This patch does not change the
situation in any way.

AFAIK, there are few users of this extension and I can see a couple
reasons why this is probably broken in Mesa anyway.

Support is removed for four reasons:
1. The implementation was broken with respect to separate blend
equations. The GL_EXT_blend_equation_separate spec says:
"If EXT_blend_logic_op and EXT_blend_equation_separate are both
supported, the logic op blend equation should be supported separately
for RGB and alpha as with the other blend equation modes."
But Mesa's implementation of GL_LOGIC_OP specifically forbids this.
2. No hardware supported by Mesa can support separate blend equations
involving GL_LOGIC_OP.
3. No applications could be found that use this extension.
4. No other Linux OpenGL drivers support this extension.

EXT_shared_texture_palette
This was also discussed at XDS 2010. However, actually making the
change was delayed because several drivers still exposed these
extensions to significant benefit (e.g., tdfx). Now that those
drivers have been removed, this code can be removed as well.
v2: A lot of bits that were missed in the previous patch have been removed.

This is the same as ARB_draw_buffers (which derived from it), except
for s/ARB/ATI/. The glapi bits were already in place, and what was
missing was just the ARB_fp part. The new Humble Bundle game "trine"
tries to use this extension without checking that it's exposed, which
this works around.

If set to year X, only report extensions up to that year. This is a
work-around for games that try to copy the extensions string to a fixed
size buffer and overflow. If a game was released in year X, setting
MESA_EXTENSION_MAX_YEAR to that year will likely fix the problem.

LUMINANCE_ALPHA_LATC2 = LUMINANCE_ALPHA_3DC, so this is easy.

The encoding/decoding algorithms are shared with RGTC.
Thanks to some magic with the base format, the RGTC texstore functions work
for LATC too.
swrast passes the related piglit tests besides two things:
- The alpha channel is wrong (it's always 1), however the incorrect alpha
channel makes some other tests fail too, so I guess it's unrelated to LATC.
- Signed LATC fetches aren't correct yet (signed values are clamped to [0,1]),
however RGTC has the same problem.
Further testing (with other of my patches) shows that hardware drivers
and softpipe work.
BTW, ETQW uses this extension.

|

|

It was only implemented in the swrast driver and probably not used by
any applications. A modern app would use a dependent/chained texture
lookup in the fragment shader.
