Hi Fabian,

	First off, your screenshots look amazing. What are you using to draw
the controls? Are you doing all the drawing with System.Drawing or
pinvoking into a windows themeing API?

  I think we can just force the parent control to render, then blit the
parents DC before rendering our control. Thats a worse case scenario,
peter and I also discussed some better methods for this.

  The Theme needs to handle both sizing and drawing. Anywhere we are not
doing this is a bug that should be fixed. Do you have specific examples?

  Once again. These look awesome! Keep up the good work.

Cheers,
