matplotlib Code

Fix mathtext bug.

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.

add disclaimer in drawlsmask docstring

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.

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