Fix memory leak when using colorbar as discovered by Darren Dale. The
(unit change) callbacks in the Axis objects were not cleared by cla(),
so they would continue to grow long lists of callbacks that reference
entire Axes objects.

Slight speed improvement in draw_quad_mesh.
........

Reduce file sizes for mixed-mode PDFs by only outputting the part of
the image with non-transparent pixels.
Minor speed improvement in MixedModeRenderer.

Support mixed-mode rendering the PDF backend. This allows some things
to be rendered as vectors and some as rasters. At the moment, mostly
as a proof-of-concept, all quadmeshes are rendered as rasters with the
PDF backend.
Also make PDF backend resolution independent.

Let to_rgba return uint8; track changes to cmap

Images require rgba as 4 uint8s, so it is more efficient
to generate these directly in to_rgba than to generate 4
doubles and convert them later.

The tracking of changes in ScalarMappable was handling
communication between objects, but was not keeping track of
when to_rgba needs to be rerun. A dictionary was added
to do this.

Add experimental "pcolorfast" for fast interactive pcolor plots

This will need more discussion and work, but it illustrates
the potential for very fast pcolor-type plotting with all
three grid types: uniform, irregular but rectilinear, and
general quadrilateral.
