DrawingCF is a System.Drawing replacement for .NET Compact Framework which utilizes GDI+ like the desktop version of System.Drawing.
The desktop version of System.Drawing uses GDI Plus functionality but the same namespace in the Compact Framework is restricted to GDI APIs. GDI Plus includes many more options for brushes, line caps, images, transformations, etc. While the GDI Plus APIs implemented
on Windows Mobile 5.x and 6.x are not as complete as those for the desktop, most of the functionality is there.
