n#797967 use only Bitmap scaling and fixes to scaling

"grfmgr" uses its own scaling functions instead of the scaling
functions available on Bitmap object. The step to use the Bitmap::Scale
for most scenarios was already made, now the "grfmgr" functions are
not used anymore.

In addition this commit fixes croping the bitmap with large zoom
levels.
