The bitmap-stretching mode defines how information is removed from bitmaps that are stretched or compressed by the StretchBlt member function.
The STRETCH_ANDSCANS and STRETCH_ORSCANS modes are typically used to preserve foreground pixels in monochrome bitmaps. The STRETCH_DELETESCANS mode is typically used to preserve color in color bitmaps.
