This can be derived from the shader caps.

All GPUs from ATI/AMD, NVIDIA, and INTEL have separate texture slots
for each shader stage.

v2: Fixed setting switch cases prior to
PIPE_CAP_MIN_MAP_BUFFER_ALIGNMENT incorrectly.

Trivial.

If any driver doesn't support this, it can use a blit after resolving
the samples.

Newer virtual HW versions support smooth/stipple/wide lines.

Ever since introducing separate sampler and sampler view max this was really
missing.
Every driver but llvmpipe reports the same number as number of samplers for
now, so nothing should break.

Just set the SVGA3dSurfaceFormatCaps flags for 3D and cube textures
when checking the texture format capabilities.  This will filter out
unsupported combinations like 3D+DXT.

This just tells the state tracker to turn on the GL_ARB_shader_texture_lod
extension.  This simply allows the GLSL compiler to emit TXL and TXD
instructions for both vertex and fragment shaders.  We already support
these opcodes in the svga driver.  Though, the shadow2DGrad() Piglit
tests are failing.

Using the map/unmap path for glTexImage is a little bit faster
than blitting.  Also, this fixes about 50 assorted piglit failures
that seem to be related to the blit version of glReadPixels.

This is the only sane solution for nv50 and nvc0 (really, trust me),
but since on other hardware the border colour is tightly coupled with
texture state they'd have to undo the swizzle, so I've added a cap.

The dependency of update_sampler on the texture updates was
introduced to avoid doing the apply_depthmode to the swizzle twice.

v2: Moved swizzling helper to u_format.c, extended the CAP to
provide more accurate information.

To track the amount of memory used by all pipe_resources (textures
and buffers).

This makes it possible to identify gl_TexCoord and gl_PointCoord
for drivers where sprite coordinate replacement is restricted.

The new PIPE_CAP_TGSI_TEXCOORD decides whether these varyings
should be hidden behind the GENERIC semantic or not.

With this patch only nvc0 and nv30 will request that they be used.

v2: introduce a CAP so other drivers don't have to bother with
the new semantic

v3: adapt to introduction gl_varying_slot enum

Initially, only softpipe/llvmpipe support SQRT.
