When using multiple color drawbuffers with blending/logicop/masking we
were overwriting color values which we still needed.

Note: not plugged into the dispatch table yet.

Note: some code disabled until dispatch table supports GL3 entrypoints.

These functions clear color/depth/stencil buffers with a value that's
passed to the function, rather than the context clear values.
For now these functions are implemented in terms of the existing
ctx->Driver.Clear() hook. In the future when we have non-normalized
integer and unsigned integer color buffer formats we'll need new
driver hook(s) to pass int and uint clear values to the driver.
Note: these functions are not hooked into the dispatch table at this time.

This is part of the GL_EXT_draw_buffers2 extension and part of GL 3.0.
The ctx->Color.ColorMask field is now a 2-D array. Until drivers are
modified to support per-buffer color masking, they can just look at
the 0th color mask.
The new _mesa_ColorMaskIndexed() function will be called by
glColorMaskIndexedEXT() or glColorMaski().
|
|
The functions are _mesa_GetBooleanIndexedv(), _mesa_GetIntegerIndexedv(), and
_mesa_GetInteger64Indexedv(). These will be called from API functions such as
glGetBooleanIndexedvEXT() and glGetBooleani_v().
Only the GL_BLEND query is supported at this time.
|
|
ctx->Color.BlendEnabled is now a GLbitfield instead of a GLboolean to
indicate blend on/off status for each color/draw buffer.
This is infrastructure for GL_EXT_draw_buffers2 and OpenGL 3.x
New functions include _mesa_EnableIndexed(), _mesa_DisableIndexed(), and
_mesa_IsEnabledIndexed(). The enable function corresponds to
glEnableIndexedEXT() for GL_EXT_draw_buffers2 or glEnablei() for GL3.
Note that there's quite a few tests for ctx->Color.BlendEnabled != 0 in
drivers, etc. Those tests can remain as-is since the mask will be 0 or ~0
unless GL_EXT_draw_buffers2 is enabled.

GLSL 1.10 disallows initializers for uniforms but GLSL 1.20 and later
allows them. This patch uses the #version directive to allow/disallow
uniform initializers.
This addresses bug 25807, but piglit also needs to be fixed to specify
the GLSL version in the shader.

This function will search the constant parameters in an effort to re-use
constant slots. For example, {1,2,3,4} and {4,1,1,2} can be stored in
one constant slot and accessed with different swizzles. The swizzle info
must be propogated though the parsing code in a few places.
Fixes Piglit "vpfp-generic tests/shaders/generic/big-param.vpfp" failure.

The wine d3d9 visual.c testcase was tripping over this and failing.
Presumably it's binding a packed depth/stencil texture to both
stencil and depth attachment points, and we make a new renderbuffer
wrapper for each in that case.
|
|
Wine's d3d9 visual.c testcase tries this a lot, so I've added some
piglit tests (fbo-nodepth-test, fbo-nostencil-test, fbo-stencil-only)
and enabled it.
