Detailed Description

A C++ wrapped around the assembler in GDRAW.DLL.

Author:

Andy_Pennell (Xara Group Ltd) <camelotdev@xara.com>

Date:

14/7/94

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.

If real GDraw is not available (e.g. Win16) then this returns FALSE from the Init function and all other member functions return failure codes.
