[Mesa-dev] [PATCH 0/5] i965: Fix glClear of layered framebuffers.

[Paul Berry]

>From section 4.4.7 (Layered Framebuffers) of the GLSL 3.2 spec:

    When the Clear or ClearBuffer* commands are used to clear a
    layered framebuffer attachment, all layers of the attachment are
    cleared.

Patch 1 adds logic to the framebuffer completeness check to record the
number of layers in a layered framebuffer, so that when we later clear
it we will know how many layers need clearing.  Patch 2 fixes the Meta
path for layered clears.  Patches 3 and 4 fix the i965 blorp path
(which is used for most color buffer clears).  Patch 5 fixes the i965
fast depth clear path.

This patch series depends on "[PATCH] glsl: Fix cross-version linking
between VS and GS.", which was sent out for review earlier today.
