i965/msaa: Set KILL_ENABLE when GL_ALPHA_TO_COVERAGE enabled.

i965 hardware needs to be informed of situations in which it's
possible for pixels (or samples) to be discarded for reasons other
than depth/stencil testing (e.g. due to an explicit "discard" in the
fragment shader).  One of these situations is when
GL_ALPHA_TO_COVERAGE is enabled, since that can cause samples to be
discarded by the color calculator when the pixel's alpha value is less
than 1.0.

buffers.

Paul Berry [Wed, 20 Jun 2012 20:40:45 +0000 (13:40 -0700)]
i965: Compute dFdy() correctly for FBOs.

On i965, dFdx() and dFdy() are computed by taking advantage of the
fact that each consecutive set of 4 pixels dispatched to the fragment
shader always constitutes a contiguous 2x2 block of pixels in a fixed
arrangement known as a "sub-span".  So we calculate dFdx() by taking
the difference between the values computed for the left and right
halves of the sub-span, and we calculate dFdy() by taking the
difference between the values computed for the top and bottom halves
of the sub-span.

However, there's a subtlety when FBOs are in use: since FBOs use a
coordinate system where the origin is at the upper left, and window
system framebuffers use a coordinate system where the origin is at the
lower left, the computation of dFdy() needs to be negated for FBOs.

This patch modifies the fragment shader back-ends to negate the value
of dFdy() when an FBO is in use.  It also modifies the code that
populates the program key (brw_wm_populate_key() and
brw_fs_precompile()) so that they always record in the program key
whether we are rendering to an FBO or to a window system framebuffer;
this ensures that the fragment shader will get recompiled when
switching between FBO and non-FBO use.

This will result in unnecessary recompiles of fragment shaders that
don't use dFdy().  To fix that, we will need to adapt the GLSL and
NV_fragment_program front-ends to record whether or not a given shader
uses dFdy().  I plan to implement this in a future patch series; I've
left FIXME comments in the code as a reminder.

Fixes Piglit test "fbo-deriv".
