The VBO module may use a real VBO or a malloc'd buffer for vertex storage.
Be careful not to accidentally replace the later with the former when drawing.
Check if using a real VBO at destroy time to prevent a double-free.
intel: Fix clears to depth_stencil texture attachments.
Broken by 0adfd1021035e90995a25ec5f20b736e55075d92, showed up as an assertion
failure in a software fallback in the shadowtex demo when we failed to
recognize the texture format.
vbo: unmap and remap immediate vbo before/after each draw.
Also use BufferData(NULL) to get fresh storage and avoid synchronous
operation where we would have to flush and wait for the fence after each
draw because of the map.
This will chew through a whole load of buffer space on small draws, so
it isn't a proper solution. Need to support a no-fence or append mapping
mode to do this right, or use user buffers.
Additional error checking.
Allow setting elements of uniform arrays. This involves encoding both
a uniform location and a parameter offset in the value returned by
glGetUniformLocation().
Limit glUniform[if]v()'s count to the size of the uniform array.
When setting bool-valued uniforms, convert all float/int values to 0 or 1.
i965: Cope with batch getting flushed in the middle of batchbuffer emits.
This isn't required for GEM (at least, yet), but the check_aperture code
for non-GEM results in batch getting flushed during emit. brw_state_upload
restarts state emits, but a bunch of the state emit functions were assuming
that they would be called exactly once, after prepare and before new_batch.
Bug #17179.
The colormask code generation had assumed that its input packed pixels were
in RGBA format. In fact, the format they're in is dependent on the
pipe color format.
Now the color format is passed in to gen_colormask(), and proper
color format-dependent SPU code is generated.
cell: Fixed bug with absolute, negate, set-negative logic in source fetch for TGSI instructions. The logic should operate on the origin channel not the swizzled channel.
