PIL uses Windows' standard "stretching mode", which appears to be
BLACKONWHITE (pick the *darkest* source pixel for each output pixel).

not sure if PythonWin allows you to call the SetStretchBltMode function
on the DC; if it does, setting the mode to COLORONCOLOR should do the
trick.

if not, use PIL's resize or transform(EXTENT) method to resize the image
before blitting it (or add a SetStretchBltMode call to PIL's libImaging/Dib.c
and rebuild...)
