Chris Wilson b9407af6a4 image: Implement high level interface. ...

Write a dedicated compositor for pixman so that we avoid the
middle-layer syndrome of surface-fallback. The major upshot of this
rewrite is that the image surface is now several times quicker for glyph
compositing, which dramatically improves performance for text rendering
by firefox and friends. It also uses a couple of the new scan
convertors, such as the rectangular scan converter for rectilinear
paths.
