From: Boyan Ding <boyan.j.d...@gmail.com>
When draw buffers are changed on a bound framebuffer, DrawBuffer(s)
hook
should be called. However, it is missing in update_framebuffer with
window-system framebuffer, in which FB's draw buffer state should match
context state, potentially resulting in a change.
Note: This seems to be needed because gallium delays creating the front
buffer. i965 works fine without this change.
V2 (Timothy Arceri):
- Rebased on merged/simplified DrawBuffer driver function
- Move DrawBuffer call outside fb->ColorDrawBuffer[0] !=
ctx->Color.DrawBuffer[0] check to make piglit pass.
