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 git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22003 a95241bf-73f2-0310-859d-f6bbb57e9c96

\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.
