i965: asst. fixes, work-arounds for FBOs and render to texture

OpenGL allows mixing and matching depth and stencil renderbuffers in
framebuffer objects while the hardware really only supports interleaved
depth/stencil buffers.  This makes for some tricky buffer management.

An extra wrinkle is the situation where the user allocates a 16bpp depth
texture or renderbuffer then tries to render to it along with a stencil
buffer.  We'd have to promote the 16bpp Z values to 24-bit Z values and
mix in the stencil values to setup the depth/stencil renderbuffer.

There's no support for that now, so always allocate 32bpp depth textures/
renderbuffers for now.

15 years agoglsl: implement loop unrolling for simple 'for' loops

glsl: implement loop unrolling for simple 'for' loops

Loops such as this will be unrolled:
  for (i = 0; i < 4; ++i) {
      body;
  }
where 'body' isn't too large.

This also helps to fix the issue reported in bug #19190.  The problem there
is indexing vector types with a variable index.  For example:
  vec4 v;
  v[2] = 1.0;  // equivalent to v.z = 1.0
  v[i] = 2.0;  // variable index into vector!!

Since the for-i loop can be unrolled, we can avoid the problems associated
with variable indexing into a vector (at least in this case).
