[PATCH 0/5] glamor: Fixes ported from the standalone tree

[Michel Dänzer]

AFAICT these are all the relevant fixes which went into the standalone
glamor tree since it was imported into the xserver tree.

Patch 4 involves changes to the PutImage path which conflict with Keith's
pending rework of that, but the other parts of it are required for patch
5 AFAICT. Patch 5 in turn could be dropped in favour of Keith's 'Add
glamor_program based copy acceleration' change in his glamor-server
branch. But either that or patch 5 is necessary e.g. to make the game
OpenTTD playable (at least on Radeons).

I've only lightly tested these so far.
