*    PURPOSE:   The sample code first creates a GWorld in a *

*               Win32 compatible pixel format (in our       *

*               example code we use k32BGRAPixelFormat).    *

*               Once created the GWorld's HDC and HBITMAP   *

*               are retrieved using GetPortHDC and          *

*               GetPortHBITMAP. The active port is selected *

*               by calling SetGWorld, and graphics rendered *

*               using the Quickdraw APIs RGBForeColor and   *

*               PaintRect. Additionally, native Win32 GDI   *

*               calls are used to render graphics into the  *

*               same GWorld. Finally, the contents of the   *

*               port is copied to a secondary HDC via       *

*               ScaleBlt, using the GWorld's HDC as a       *

*               source. Note that the HBITMAP and HDC are   *

*               owned and managed by the GWorld, and are not*

*               disposed of.                                *

*                                                           *

*               (code taken from Ice Floe Dispatch #16      *

*               from the QuickTime web site)                *
