VideoScaler._2d

Scale a rectangle of pixels in src with src_stride to dest with dest_stride using the horizontal scaler hscaler and the vertical scaler vscale.

One or both of hscale and vscale can be NULL to only perform scaling in one dimension or do a copy without scaling.

x and y are the coordinates in the destination image to process.
