wglShareLists is a little picky -- it seems to check if it has exclusive
access to a lock, and fails if it doesn't.
This allows the texture to be shared with all windows.

Match what autotools and other build systems do by default.

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flush, causing transfer data to be outdated/clobbered.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.

Transparency is not relevant for this example, and leads to distraction
due to different results in alpha visuals, when capturing images to disk.

When the -arb option is specified we use GL_ARB_framebuffer_object intead
of GL_EXT_framebuffer_object.
For some vendors' OpenGL it's important to call the ARB entrypoints
instead of the EXT entrypoints to get correct behaviour. Use some
function pointer tricks to do this (instead of GLEW).

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.

Reversed component order.
This fixes glean depthStencil test failures for PIPE_FORMAT_Z24S8_UNORM
