//
// (1) RemoveFrameRectFilter reads a 100x50 region of the input.
// (aInputWriteRect captures this fact.) The remaining 50 rows are ignored
// because they extend off the bottom of the image due to the frame rect's
// (50, 50) offset. The 50 columns on the right also don't end up in the
// output, so ultimately only a 50x50 region in the output contains data
// from the input. The filter's output is not 50x50, though, but 100x100,
// because what RemoveFrameRectFilter does is introduce blank rows or
// columns as necessary to transform an image that needs a frame rect into
// an image that doesn't.
//
// (2) DownscalingFilter reads the output of RemoveFrameRectFilter (100x100)
// and downscales it to 20x20.
//
// (3) The surface owned by SurfaceSink logically has only a 10x10 region
// region in it that's non-blank; this is the downscaled version of the
// 50x50 region discussed in (1). (aOutputWriteRect captures this fact.)
