Optimizations for updating Image and GeoFeature plots #40

Closed philippjfr closed 8 years ago

philippjfr commented 8 years ago

Rather than redrawing a pcolormesh on each frame the GeoImagePlot now updates the artist directly. This only works because the extents of the colormesh shouldn't change across a single cube. To be completely safe I could request a full redraw if the lat/lon coordinates change but I don't think it's necessary. I've also avoided updating the the GeoFeature on each frame as it is expected to be static.

If someone thinks either of these assumptions isn't valid I could check more explicitly if things are unchanged and revert to the old behavior if they do not hold.

There are some issues with the projection, so this PR shouldn't be merged for now.
