[PATCH 0/4] xv: Fix auto key color fill with reput image & code clean up

[Pauli]

From: Pauli Nieminen <ext-pauli.nieminen at nokia.com>

Following patches were created while I was fixing incorrect order of auto color
key filling and window background painting in window resize.

Problem was that reput image would fill color key in reput but window background
painting only happens in WindowExposures hook. WindowExposures would be good
place to call reput after background painting but it isn't called for every clip
change.

Then I decided that it would be simpler to only use ClipNotify hook to mark
ports that require reput. Reput is then actually done in PostValidateTree
hook. 

Pauli Nieminen (4):
  xf86/xv: Remove copy paste code.
  xf86/xv: Remove unused GC pointers
  xf86/xv: Use PostValidateTree to do reput
  xf86/xv: Only register PostValidateTree hook when there is work to do
