cc: Fix animated filter render surface check

cc: Fix animated filter render surface check

The render surface calculation wasn't taking into account animated
filters.  These are animations which will eventually set a filter, but
the filters on the layer are empty at render surface calculation time.

This is just a missed case in render surface calculation, as it used
to be handled naturally on the compositor thread after the filter got
added.

Ah nice - thanks! This'll give much better errors.
