NEW FEATURE: Fix color bounds and others during animation

[Chilipp]

Summary

data-driven formatoptions should be fixed during the animation

Reason

Otherwise the plot limits changes all the time

Detailed explanation

The following formatoptions should be fixed:

• xlim, ylim
• bounds, vbounds
• xticks, yticks, cticks, vcticks

Note that this cannot be implemented before psyplot/psyplot#21 is implemented.

[Chilipp]

I also like your idea @MuellerSeb from psyplot/psy-view#11 (comment) to only adjust min and max of the color bounds. This should be easy to implement, too in such a framework. It would not work for the other formatoptions, though

[MuellerSeb]

Another idea would be to check, if value ranges are given with the data:
http://cfconventions.org/Data/cf-conventions/cf-conventions-1.8/cf-conventions.html#missing-data

there is a convention for netCDF files including this. I think, that is the standard procedure of ncview.

[Chilipp]

Good idea. You mean the actual_range netCDF attribute?

yepp! ;-)
