Z testing now works with i915 driver.
Add gl_renderbuffer::surface pointer (and reverse pointer).
Remove intel_surface and xmesa_surface types - no longer used.

bounds.
This prevents rendering out of bounds when the viewport is partially outside the surface bounds.
|
|
|
|
The cliprect depends on the scissor rect (if enabled), otherwise the drawing
surface bounds.
|
|
could be, but sufficient for now.

something
|
|
|
|
Also added draw_stage::reset_line_stipple(). There may be a better way
of doing that though.

The demos/fslight.c demo runs now.
|
|
const/linear/perspective interpolation in shade_quad().
|
|
|
|
Handling of constants might change. For now, the st_fragment_program struct
contains a pipe_constant_buffer (not a pointer).
|

|
|
Fix align128 bug.
|
|
Not sure the generated program looks correct though...
|
|
Not really signficant now since draw_flat stage copies the provoking
vertex color to all prim verts.
|
|
|
|
|
|
right thing.

Don't bother trying to save a small memcpy.

This removes the notion of multiple color buffers from all other stages.
Will need a bit more work when shaders with multiple render targets arrive.

Updated comments/questions about area vs. prim->det.

Using floats (and float->ushort->float conversion) introduces errors.
Only GLushort depth buffers work for now...
