[PATCH 0/5] Document screen proc wrapping and fix places where it was wrong

[Keith Packard]

Here's the patches I proposed which split the fixing of the block
handler wrapping into five individual fixes.

 [PATCH 1/5] Document how to correctly wrap screen procedures

Adds the giant comment to scrnintstr.h

 [PATCH 2/5] hw/xfree86: Fix block handler wrapping in xf86Rotate

Fixes the demonstrated bug

 [PATCH 3/5] mi: Fix block handler wrapping in miSprite

Fixes incorrect wrapping of the BlockHandler in miSprite. Note that
all other wrapping in misprite was already correct...

 [PATCH 4/5] hw/xfree86: Fix VGA arbiter screen proc wrapping

Fixes all of the screen wrappers in the VGA arbiter.

 [PATCH 5/5] hw/xfree86: Let xf86Rotate leave the BlockHandler

Finally, removes the rotate block handler when possible.
