vcl: try to fix sizes in ImplBlendToBitmap()
Since commit 2f84b420e0428693fb2d45b68afdc9023dfc08bc,
sw_unoapi test sw.SwAccessibleEndnoteView crashes while trying to blend
a 1107x8 Bitmap into a 97x8 Bitmap; it's not obvious that any of the
parameters passed in is wrong and it's odd that ImplBlendToBitmap()
would use rSrcBuffer.mnHeight and rDstBuffer.mnWidth; presumably
it should use both height and width of the same buffer.
