List of things to do some time in the future. Mostly notes to myself.

- progressive image loading: GIF animations and PNG images still needs to be
  done.

- Try to optimize XImage usage in the progressive image loader. Should find a
  better way to do this, currently progressive image loading is terribly
  resource heavy.

- fix X Protocol errors for color freeing 4bit StaticColor visual. Haven't got
  a clue how to tackle this though.

- HTML tables!
  19-09-97: it's in the works

- more work on the Programmer's Manual

- XmImageCreateFromInfo: add support for the ImageBackground flag on the
  XmImageConfig struct for animations. Background color substitution already
  works for single images and single frame selection for animations.

- add support for ImageWorkSpace XmImageConfig flag.

- XmCreateHTMLDialog, XmCreateHTMLMessageBox

- text flow around images
