Add color module support for Busy Theme

There is one thing that might not even be doable with the patched color module.
There is a place where the dropshadow overlaps the gradient of the blue background bar:

Which results in this background image:

Could we circumvent this by providing the dropshadow as a transparent png and combining it with the gradient using the imagecopy function? http://php.net/manual/de/function.imagecopy.ph

Eclipsegc: Tried out your implementation, and it only partially worked. The fonts are recolored, but not the Graphics. Looking into the .inc file, i see that the slices are not done yet. Maybe you need some more information from me like you said recently?

Here is the error message it gives me:
