The Microsoft Windows graphics escapes provide graphics support that is
otherwise not available through graphics-device interface (GDI).
Applications use graphics escapes to perform device-dependent operations
that are not supported by GDI. Applications call the Escape function
(GDI.38) to initiate an escape and GDI calls the device driver's Control
function to complete the escape.
 
The following topics provide useful information about the graphics escapes:
