Add a layer (FBO) cache.

The cache is used to draw layers so that a new
texture does not have to be recreated every time
a call to saveLayer() happens.

The FBO cache used a KeyedVector, which is a bad
idea. The cache should be able to store several
FBOs of the same size (this happens a lot during
scrolling with fading edges for instance.) This
will be changed in a future CL.
