I just did some profiling using oprofile and it pretty much confirms
that all of the trouble is inside Cairo (this is on an Intel graphics
chip). Having said that, I believe we are going about using Cairo the
wrong way. The long term solution is to blit the blocks graphics to an
offscreen pixmap on a resize event and perform the game rendering with
pixmaps while playing. When another resize event happens, discard the
old pixmaps, reblit the blocks to new pixmaps and resume play.

In the short term, I agree that we should kill gradients.

Sounds good. I'll test today; I see that all the fixes are checked in now.
