Stephan Aßmus f7e1df7560 * get rid of RGBColor usage where it is not needed, this simplified many things,
possibly making them a little faster too
* mess with decorator button size calculation to make the whole layout scale
  more agreeable with the font size (no more fixed offsets/insets), but it
  is work in progress
* DefaultDecorator no longer allocated the border color array, it is part of
  the object now
* small memory footprint optimizations in ViewLayer, Decorator and WindowLayer

\class ServerBitmap ServerBitmap.h
\brief Bitmap class used inside the server.
This class is not directly allocated or freed. Instead, it is
managed by the BitmapManager class. It is also the base class for
all cursors. Every BBitmap has a shadow ServerBitmap object.
