ANN: matplotlib-0.65.1

This is primarily a bug-fix release from 0.65, though a couple of
little features managed to sneak in

- 4x image speedups for large images

- figimage bug fixed

- fixed some bugs which caused the colorbar not to update properly
   when changing colormap interactively

- refactored axes management to support delaxes, which deletes, as
   opposed to clears, a specified axes. Default to current axes

- tkagg's classic and new-fangled toolbars are now embeddable.

- extended the new set/get introspection features to more classes

- fixed some tkagg flakiness on win32 regarding unusual uses of show.

- new cross backend animation idiom in examples/anim.py - use
   interactive mode rather than timers/idle handlers.

- deferred some initializations in dates and colors modules for
   faster load times.

Enjoy!

This is a biggie!! Ladies and gentlemen, my impression is that imshow
is now at least as fast as, and perhaps faster than, DS9 for
astronomical image display. (I'm looking at 1024 square full disk solar
images.) Nice job, John.

Happy happy to all,
Steve

I therefore propose that we start developing a Python version of DS9. The benefits of a Python version based on matplotlib are TrueType fonts (with arbitrary text rotation), alpha blending, and direct support for numarray.

Sounds like an interesting project. The first item I'd have on a list
of desired features is, surprise, the ability to load multiple aligned
images and blink between them.
