respect the origin implied by the bitmap contexts affine tranformation matrix

Implements the changes requested by reviewers to go though
CGPointApplyAffineTransform to create the origin data.  Personally I don't like
this patch as much as the previous one because it requires yet another call to
CGPointApplyAffineTransform in order to determine if the axes are flipped. 
However it is simply a mater of taste and is functionally identical;  it may be
more clear to some maintainers what is happening.
I also now treat Y-Axis and and X-Axis identically even though inverting the
X-Axis would be unusual.
