matplotlib Code

Support mixed-mode rendering in the SVG backend.

Remove draw_arc (which isn't in the new backend renderer interface).

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.
