matplotlib Code

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.

fix drawlsmask for 'moll','robin' and 'sinu' projections.

Slight speed improvement in draw_quad_mesh.

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.

Removing trailing whitespace so a merge from trunk will be possible.

Fix problem with 0-line width drawing in Postscript. (Thanks Ben North).

docstring tweak.

the relevant projection parameters for each projection.
