Plot with advanced compositing

The way flatmap plotting works in pycortex is to create different image layers (data, ROIs, sulci, etc) and overlay each on top of the other. Usually, quickflat.make_figure() handles all this for you, but each layer can be manipulated independently for fancier effects with the quickflat.composite sub-module.
