Detailed Description

To put a C++ wrapper around the GDraw DLL. Also allows non-Gavin originated GDraws (e.g. XDraw) to be dropped in as required. This class is almost a pure base class - inherited classes have to have their own functions for almost everything.

The caller should only ever need one instance of one of these (really its inherited brothers) and keep it around for the duration of the program. The keeper of the pointer to this is GRenderRegion.

With the exception of the ConvertBitmap function, this class could be put in the kernel. Maybe it should. Perhaps. Ish.
