I want to build an application that

1. has a  complex custom shape
2. smoothly changes its shape from one state into another

First of all I thoght I coud use Crgn. Creating shapes is not the problem
with it, but if I want to animate it (changing the shape step by step in the
onTimerEvent) the applicationwindow flickers.

Can anyone give me a hint?

Thanx,

Robert Ludewig
