fpGUI doesn't use fpImage yet, but I did borrow the StretchDraw() code
from there. And yes, you can specify a whole bunch of other
interpolations to use. If memory serves me well, fpGUI has a few more
interpolations than fpImage. When I start implementing fpImage support
in fpGUI, I will contribute those to FCL.
