Bugs

When you use a filter and then do "image source", Sherpa sets up an incorrect data space when creating the FITS file to display.

What was supposed to be a 2D image gets displayed as a 1D image, e.g., if "image source" should have resulted in a 100x100 image, a 10000x1 image is actually displayed.

The problem goes away if you say "notice all" before the image command. Also, "image fit" still seems to work correctly.
