Both EXT_fbo and ARB_fbo agree on this. Fixes a segfault in the metaops
mipmap generation in Intel for SGIS_generate_mipmap of S3TC textures in
Regnum Online.
Bug #21654.

The _Enabled field isn't updated at the point that DrawBuffers is called,
and the Driver.Enable() function does the testing for stencil buffer
presence anyway.
bug #21608 for Radeon

The docs actually explain this, but not in a terribly clear manner.
This nearly fixes the piglit cubemap testcase, except that something's
going wrong with the nearest filtering at 2x2 sizes in the testcase.
Looks good by visual inspection, though.

I don't have a testcase for this, but it seems clearly wrong.

Before, if the VP output something that is in the attributes coming into
the WM but which isn't used by the WM, then WM would end up reading subsequent
varyings from the wrong places. This was visible with a GLSL demo
using gl_PointSize in the VS and a varying in the WM, as point size is in
the VUE but not used by the WM. There is now a regression test in piglit,
glsl-unused-varying.

This comes from a radeon-rewrite fallback fix, but may also fix stencil
clear failure when the polygon winding mode is flipped.

This looks to be a win of a few percent in cairogears with new vbo code,
thanks to not polluting caches.

The first time a context is bound to a drawable, the viewport and scissor
bounds are initialized to the buffer's size. This is actually a bit tricky.
A new _mesa_check_init_viewport() function is called in several places
to check if the viewport has been initialized. We also use a new
ctx->ViewportInitialized flag instead of the overloaded
ctx->FirstTimeCurrent flag.

Two parts to this:
One we don't keep pointers to possibly freed memory anymore once we unbind the
drawables from the context. Brian I need to figure out what the comment
you made there, can we get a glean/piglit test so we can fix it properly?
If the new gc is the same as the oldGC, we call the unbind even though
we just bound it in that function. doh.

For the TXP instruction we check if the texcoord is really a 4-component
atttibute which requires the divide by W step. This check involved the
projtex_mask field. However, the projtex_mask field was being miscalculated
because of some confusion between vertex program outputs and fragment
program inputs.
1. Rework the size_masks calculation so we correctly set bits corresponding
to fragment program input attributes.
2. Rename projtex_mask to proj_attrib_mask since we're interested in more
than just texcoords (generic varying vars too).
3. Simply the indexing of the size_masks and proj_attrib_mask fields.
4. The tracker::active[] array was mis-dimensioned. Use MAX_PROGRAM_TEMPS
instead of a magic number.
5. Update comments, add new assertions.
With these changes the Lightsmark demo/benchmark renders correctly, until
we eventually hit a GPU lockup...

For some triangles we can generate quads which lie just outside the
surface bounds. Just check the quad's mask before trying to emit/process
the quad.
Fixes failed assertion in Lightsmark.

A 0 by 0 viewport size is legal. Don't clamp against lower bound of one.
The error checking earlier in the function prevents negative values.

The results were incorrect for some negative values of A.

Render results are only visible when the render cache is flushed.
softpipe_is_texture_referenced must reflect that or transfers to/from the
textures bound in the framebuffer won't be proceeded of the necessary
flush, causing transfer data to be outdated/clobbered.
This fixes conform drawpix test with softpipe.

Before, if a vertex shader's outputs didn't exactly match a fragment
shader's inputs we could wind up with invalid TGSI shader declarations.
For example:
Before patch:
DCL OUT[0], POSITION
DCL OUT[1], COLOR[1]
DCL OUT[2], GENERIC[0]
DCL OUT[3], GENERIC[0] <- note duplicate [0]
DCL OUT[4], GENERIC[2]
After patch:
DCL OUT[0], POSITION
DCL OUT[1], COLOR[1]
DCL OUT[2], GENERIC[0]
DCL OUT[3], GENERIC[1]
DCL OUT[4], GENERIC[2]

Actually, after spotting this problem, I realized this is unreachable
code. However don't bother to enable this fast path now, given the normal
path is working just fine.
