Bugfix for broken_barh demo

Fix memory leak and increase performance in quadmesh drawing (Agg)

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.

Further speed improvements. Quadmesh extension code (still not as
fast as the old version, for various reasons.)
Fix bugs in quadmesh masking in PDF and PS backends.

Further speed improvements. For collections, now has faster ignoring
of elements that aren't provided, such as offsets. Paths now do not
even store the "default" codes array -- which is MOVETO followed by N
LINETOs. These are generated automatically by the iterators if no
codes array is provided. (Should also result in significant memory
savings for graphs with many points.)

Speed up pcolor_demo.py "benchmark" initialization by a factor of 2.
Cache the automatically created path codes by their length.
pcolor, quadmesh etc. create lots of polylines of the same length, and
there is no need to create a new identical codes array each time.
(Definite speed improvement, incredible memory improvement).
Change the default behavior to create open paths (which don't result
in a memory copy). Fix places that were relying on
automatically-created closed paths to create closed paths themselves
(and thus avoiding a copy).

Oops -- this shouldn't have been committed.
