[Developers] IOJpeg and Carpet

[Erik Schnetter]

During this week's Cactus phone call, we shortly discussed visualising 
mesh refinement simulations with IOJpeg or IOMpeg.

When mesh refinement is used, the grid spacing is not the same 
everywhere in the domain, and hence using hyperslabbing to access data 
does generally not work.  Additionally, the interesting region of the 
simulation is just a part of the simulation domain.

One way out is to create the pictures through interpolation.  Let the 
user define an interesting range, e.g. x from xmin to xmax and y from 
ymin to ymax, and interpolate the simulation data onto a regular grid 
in this rectangle.  These data can the converted into a jpeg picture or 
mpeg frame as usual.
