matplotlib Code

Adding calls to gc.restore() whenever new_gc is called. This is necessary for the Mac OS X and the Cairo backend to work correctly. Also, updating the Mac OS X backend to be consistent with recent changes in SVN. See issue 2844845 on sourceforge.

Use numpy to generate the PDF shading triangles stream, which should be faster and more portable than using struct.

Add CHANGELOG entry about Gouraud shading

Small fix to Gouraud triangles in pdf

Add "draw_gouraud_triangles" (note the 's') backend method. Add initial support in Pdf backend (working in xpdf and evince, but not in acroread, strangely).

Colormap work:
- Simplify data for existing colormaps
- Add a few colormaps
- Allow setting of gamma
- Allow using functions

Pull _parse_args out of Quiver and Barbs classes, as we have multiple, diverging copies of the same code. Now the shared code will actually be shared.

Use atleast_1d instead of asanyarray. This allows passing in scalars to quiver/barbs.
