1. About
 
 DGDI32 is part of HX's Win32 emulation. DPMILD32 will load this dll if 
 module GDI32 is imported. Support for GDI32 is only rudimentary, though,
 and most Win32 GUI apps won't run. Main purpose is to support simple
 applications which just need the basics (bitmaps, pens, brushes,...).
 

 2. Supported Functions
 
 Please note that if a function is not marked as dummy this doesn't mean
 it is fully implemented.
