This is actually not as trivial as i originally thought. While the colors can be restored easily, using css-filters (for opacity) also resets the shapes scaling on re-inserting it into the dom (ignoring its parents coordsize attribute). I have not yet found a bulletproof way around that problem.

Fixed in CVS HEAD.

- The missing colors where fixed by improving the restore-mechanism in VML.js and GraphicsMixin.js.
- The incorrect scaling was fixed by using a DIV as VML-canvs instead of a vml-group. This also made "setLayoutMode" unnecessary.
- Also did some minor refactorings to VML.js in the process and included Tests.

These changes will also be very helpful should we extend the GC/VML features.
