   4 Subject: [PATCH] Allow i965 compositing to target A8 buffers
   5
   6 Without this, software fallbacks were being forced for glyph
   7 rendering. This change appears to eliminate the fallbacks,
   8 (but slows glyph rendering down overall, presumably due to
   9 slow compositing currently in the i965 driver).
