* Added a new class BAffineTransform, currently in the BPrivate namespace
and the inofficial "shared kit".
* Extended BPolygon to be transformable by a BAffineTransform.
Thanks a lot!
Minor fixes by myself:
* The class accidentally still derived from agg::trans_affine.
* Added then missing comparator operators.
* Swapped the BPoint* and count arguments of Apply(), since that seems
to be the more common order in the other Be API.
