Resolves: #i121233# Added bitmap scaling methods BMP_SCALE_SUPER

Browse Source 
added from symphony, also BMP_SCALE_LANCZOS, BMP_SCALE_BICUBIC,
BMP_SCALE_BILINEAR and BMP_SCALE_BOX.

Changed defaults for internal scalings, enhanced PDF export when reduched DPI
is used, added BMP_SCALE_BESTQUALITY and BMP_SCALE_FASTESTINTERPOLATE as new
default for Bitmap::Scale

(cherry picked from commit bf734a151dc5169b65cf5d2a127e4142b765326c)
