MMaskScrollBitmapToShape X1.w,Y1.w,Width.w,Height.w,X2.w,Y2.w[,SourceBitmapNum.w] ; Copy bitmap to shape & cut

Does the same as MMaskScroll except that the source of the operation will be a
chunky Bitmap and the destination will be a chunky Shape. The Bitmap's image will
be blitted to the shape using the Bitmap's stencil as a mask.
