Remove ImplCreateScaled and ImplCreateRotatedScaled
ImplCreateScaled and ImplCreateRotatedScaled are now not used anymore,
so they can be removed.
Hi Tomaž, great fixes there - I especially like the sinc interpolation changes. Just a remark to ImplCreateRotatedScaled, that *did* have some performance benefits, by having only *one* pass over the image.

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.
See above - there are nice, separable algorithms for bitmap manipulations, that can do affine transformations in 2-3 runs, e.g. Wolberg, "Digital Image Warping" is a classic - if you like hacking on pixel processing, there's some nifty stuff to do still (I'd also love to have basebmp used for those things some more, avoiding virtual function / callback calls for every pixel). Want to poke me on irc for some pointers? Cheers, -- Thorsten
