Change drawBitmapRect to take a float-src-rect instead of integer-src-rect. This

allows the client more control over the scaling. Because of virtual overrides
and wanting to keep the old call-sites up and running, this CL renames the
virtual entry-point to drawBitmapRectToRect, and downgrades drawBitmapRect to
a non-virtual helper function.

The implementation is to use the float-rect for computing the matrix, but still
cons-up an integer rect for the purposes of subsetting the original bitmap. We
do this by calling float_src->roundOut(&int_src) so that we include all
(partially) covered src pixels.

No change needed on SkDevice, since that signature is explicitly passed the
computed matrix.
