This array was mistakenly dimensioned with VERT_ATTRIB_MAX (32) but it
should really be MAX_VERTEX_GENERIC_ATTRIBS (16).
The generic vertex attributes are in addition to the conventional arrays
(except in NV vertex program mode- they alias/overlay in that case) so
the total of all conventional attributes plus generic attributes should
total 32 (not 48).
When a vertex shader uses generic vertex attribute 0, but not gl_Vertex,
we need to set attribute[16] to point to attribute[0]. We were setting the
attribute size, but not the pointer.
Fixes crash in glsl/multitex.c when using the VertCoord attribute instead
of gl_Vertex.
It's possible to hand a GL_COLOR_INDEX/GL_BITMAP image to glTexImage3D()
which gets converted to RGBA via the glPixelMap tables.
This fixes a failure with piglit/fdo10370 with Gallium.
The generic_array[] is 16 elements in size, but the loop was doing 32
iterations. The out of bounds array write was clobbering the following
inputs[] array but as luck would have it, that didn't matter.
We don't really implement vertex weights but in the VBO code this
fixes and odd case for the legacy_array[] setup. Before, the
vbo->draw_prims() call was always indicating that the vertex weight
array was present/enabled when it really wasn't.
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.
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.
Fixes segfault on an fbo.c negative test for FBO with texture width/height
of 0. Previously we just tested for border != 0 to work around this
segfault.
