sample programs which uses shape window.
See 'shapewin.txt' and sample sources how to use shape window
control.

treys.exe 'xeyes' look-a-like

tranime.txt
treyes.txt
Notes that these sample program eat lot of CPU. It bit heavy on home
PC (486/66), but not so heavy on company's (working) Pentium 100
PC. Anyway, large bitmap, complicated bitmap result slow down your
machine. So before you use large, complicated bitmaps, try little
bitmaps first.
