ok, I'll see what I can do. I will say that when using large projection
matrices, things are slow. There is no real way around this, since we have
to go through every pixel in the matrix and assign it a value. However, I
have a future idea that will make it better:
1. leave the resolution at <= the screen resolution.
2. have the datasource query the current kst2dplot window for the current
zoom range. (need to work out details here)
3. have a button in the datasource that when clicked will "project to current
4. the user can now zoom in and out until they get to an interesting feature.
They click the button and the map gets re-rendered at higher detail.

ok, so basically an example data file and a corresponding *.kst file that we
can just open and play around with?

so you write some code that actually goes and manipulates the widgets and
dialogs? sounds like it would be similar to watching a chess computer play
