### GreDrawRLE - Remarks

GreDrawRLE is called by the area fill code in the graphics engine. The calling function uses the driver's CAPS_ADDITIONAL_GRAPHICS/CAPS_CLIP_FILLS field, which is queried during the first instance of DevOpenDC. If it is set, the data delivered to GreDrawRLE has already been clipped and the COM_ PRECLIP flag will be set in the flag's WORD of the function number. All coordinates are passed as screen coordinates.
