Title: Blendmodes

Add support for layer blend modes (Layer Properties Dialog).

As part of setting up for this, I rewrote a chunk of the canvas, which should now be faster than before. Before, it did a Cairo paint to the screen for each layer, now we build all the layers onto the canvas, and paint the whole thing at once. Also removed the additional Cairo paint for the pixel grid.
