To allow meta acceleration operations to use sampler objects the

Because the extension doesn't have any hardware dependencies it is

This is a cleanup for ARB_transform_feedback3, where
GL_MAX_TRANSFORM_FEEDBACK_BUFFERS is introduced for interleaved attribs and
has the same meaning as GL_MAX_.._SEPARATE_ATTRIBS for separate attribs.
Also, the maximum number of TFB buffers is reduced from 32 to 4, which makes
this patch useful even without the extension.
I don't know of any hardware which can do more than 4.

gl_ClipDistance needs special treatment in form of lowering pass
which transforms gl_ClipDistance representation from float[] to
vec4[]. There are 2 implementations - at glsl linker level (enabled
by LowerClipDistance option) and at glsl_to_tgsi level (enabled
unconditionally for gallium drivers). Second implementation is
incomplete - it does not take into account transform feedback (see
commit 642e5b413e "mesa: Fix transform
feedback of unsubscripted gl_ClipDistance array" for details).
There are 2 possible fixes:
- adding transform feedback support into glsl_to_tgsi version
- ripping gl_ClipDistance support from glsl_to_tgsi and enabling
gl_ClipDistance lowering on glsl linker side
This patch implements 2nd option. All it does is:
- reverts most of the commit 59be691638
"st/mesa: add support for gl_ClipDistance"
- changes LowerClipDistance to true
Fixes Piglit tests "EXT_transform_feedback/builtin-varyings
gl_ClipDistance[{2,3,4,5,6,7,8}]-no-subscript" at least on nv50
and evergreen cards.
If the PIPE_CAP_PRIMITIVE_RESTART screen param is not set, then enable

This change is not exactly equivalent (sometimes we checked for non-zero,
sometimes if >0 or >1), but the behavior shouldn't change, because all drivers
report 0 for unsupported CAPs.
Exposing CAP_STREAM_OUTPUT_PAUSE_RESUME without CAP_MAX_STREAM_OUTPUT_BUFFERS
is a driver bug and st/mesa does no checking if the latter is supported as
well. Drivers must report CAPs consistently.
v2: make the array const
v2: handle the cap in r300 and r600 as well
Additional info for r600g:
The env var R600_GLSL130=1 enables GLSL 1.3.
Along with R600_STREAMOUT=1, it enables full GL 3.
It always had the same value as ctx->Extensions.EXT_framebuffer_sRGB.

For ARB_color_buffer_float. Most hardware can't do it and st/mesa is
the perfect place for a fallback.
The exceptions are:
- r500 (vertex clamp only)
- nv50 (both)
- nvc0 (both)
- softpipe (both)
We also have to take into account that r300 can do CLAMPED vertex colors only,
while r600 can do UNCLAMPED vertex colors only. The difference can be expressed
with the two new CAPs.
This just fixes up the enables for native integers and EXT_texture_integer
support in st/mesa.
It also set the MaxClipPlanes to 8.
We should consider exposing caps for MCP vs MCD, but since core
mesa doesn't care yet maybe we can wait for now.
v2: use 32-bit formats as per Marek's mail.
v3: add calim's fix for INT_DIV_TO_MUL_RCP disabling.

Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
The motivation behind this is to add some self-documentation in the code
about how each CAP can be used.
The idea is:
- enum pipe_cap is only valid in get_param
- enum pipe_capf is only valid in get_paramf
Which CAPs are floating-point have been determined based on how everybody
except svga implemented the functions. svga have been modified to match all
the other drivers.
Besides that, the floating-point CAPs are now prefixed with PIPE_CAPF_.
The code expects the geometry shader to be NULL.
We don't have geometry shaders now, but it's good to be prepared.
v2: check for support in the cso context
