* Rewrote the drawing code to be able to force a redraw and to invalidate the
background. This fixes the ttoggle_panel redraw problems.
* Removed the no_redraw label hack
* Updated the WIKI comment blocks to fix some typos and add some forgotten info.
Drawing on the panel still has glitches.
Events are send to the panel not to the widget.
Sapient sorry for breaking the coding standard too lazy do convert the
0's ;-).
