Merge lp:~smspillaz/compiz-animation-plugin/compiz-animation-plugin.fix_976469 into lp:compiz-animation-plugin

[Sam Spilsbury]

== Problem ==

The animation plugin was setting PAINT_WINDOW_TRANSFORMED_MASK even when it didn't need it, which would confuse other plugins

== Solution ==

Added a vfunc to determine whether or not we actually need to do that

Fixes LP#976469

[Daniel van Vugt (vanvugt)]

First observation: requiresTransformedWindow() should be const.

[Daniel van Vugt (vanvugt)]

Tests OK. No obvious regressions, though I also don't see any shadows being clipped at all.

review: Approve

[Daniel van Vugt (vanvugt)]

Hmm, I will approve this again, but first please:

1. Remove " // TODO: should only happen for distorting effects"
2. Consider making requiresTransformedWindow() const.

review: Needs Fixing
