glsl compiler will not generate OPCODE_SWZ, and as a first step it would
be translated away to a MOV anyway (why?), but later internally this opcode is
generated (for EXT_texture_swizzling).

We currently don't have support for SGI_swap_control for direct
contexts with DRI2, so disable reporting the extension. Reporting
the extension, and then having glXSwapIntervalSGI() "succeed"
but do nothing can confuse applications.

Be clearer that this is the number of generic vertex program/shader
attributes, not counting the legacy attributes (pos, normal, color, etc).

Call the _mesa_set_enable() functions instead of driver functions, etc.
Also, add missing code for 1D/2D texture arrays.

If we're running a vertex program to emulated fixed-function, we still need
to treat vertex arrays/attributes as if we're in fixed-function mode.
This should probably be back-ported to Mesa 7.5 after a bit more testing.

When a GLSL sampler reads from an incomplete texture it should
return (0,0,0,1). Instead of jumping through hoops in all the drivers
to make this happen, just create/install a fallback texture with those
texel values.
Fixes piglit/fp-incomplete-tex on i965 and more importantly, fixes some
GPU lockups when trying to sample from missing surfaces. If a binding
table entry is NULL, it seems that sampling sometimes works, but not
always (lockup).
Todo: create a fallback texture for each type of texture target?

The CALL_DrawArrays was leaking the clear's primitives into the display
list with GL_COMPILE_AND_EXECUTE. Use _mesa_DrawArrays instead, which
doesn't appear to leak. Fixes piglit dlist-clear test.

Fixes #22181. R200 requires this since DP4 is used in hw tnl mode.
R300 prefers it (should be faster due to no instruction dependencies), but
both methods should be correct (when sw tcl is used though, MUL/MAD might
be faster). Probably doesn't make much difference for R100 since vertex progs
are executed in software anyway, but let's just keep it the same there too.

The alpha value wasn't set at all before so we got unpredictable results.
Note that we don't currently obey GL_DEPTH_TEXTURE_MODE in the state
tracker. For now, we return the result in the default mode (r,r,r,1).

It is expected to loose precision here.

Using uintptr_t as intermediate type for pointer -> integer conversions is
easier to understand and does not cause any size mismatch warnings.
uintptr_t is part of C99, and we already provide a suitable replacement
definition for all platforms we care about.

Avoids warnings on 64bit builds.
Use regular unsigned since that's what gallium expects, but use a
typedef to facilitate possible changes in the future.

In multithreading stw_call_window_proc can be called by a thread other
than the thread where the context is bound.

Not only for cosmetic reasons, but also because we need to set the
SetWindowsHookEx hook for threads created before the DllMain is called
(threads for each we don't get the DLL_THREAD_ATTACH notification).

This was misspelt as glFramebufferTexturLayer (missing e), causing
conflicts with the correctly spelt version in glext.h and extfuncs.h.

Mesa and gallium both have a definition of this macro

With 1D textures, GL_TEXTURE_WRAP_T should be ignored (only
GL_TEXTURE_WRAP_S should be respected). But the i965 hardware
seems to follow the value of GL_TEXTURE_WRAP_T even when sampling
1D textures.
This fix forces GL_TEXTURE_WRAP_T to be GL_REPEAT whenever 1D
textures are used; this allows the texture to be sampled
correctly, avoiding "imaginary" border elements in the T direction.
This bug was demonstrated in the Piglit tex1d-2dborder test.
With this fix, that test passes.

One warning message:
drm_i915_getparam: -22
was still being sent to fprintf(). This causes all Piglit tests to fail,
even with MESA_DEBUG=0.
Using _mesa_warning() to emit the message allows the general Mesa controls
for messages like this to be applied.

When out of memory (in at least one case, triggered by a longrunning
memory leak), this code will segfault and crash. By checking for the
out-of-memory condition, the system can continue, and will report
the out-of-memory error later, a much preferable outcome.

If there is no shared context, there is no purpose in rebinding the same
texture. In some artificial tests this improves performance 10% - 30%.

This saves doing swtnl from uncached memory, which is painful. Improves
clutter test-text performance by 10% since it started using VBOs.

Noticed while debugging a weird 1D FBO testcase that left its existing
viewport and projection matrix in place when switching drawbuffers. Didn't
fix the testcase, though.

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.

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 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.
