/* The expand trick explained:
*
* The expand plugin is meant to take frames of arbitrary aspect ratio and
* converts them to 4:3 aspect by adding black bars on the top and bottom
* of the frame. This allows us to shift overlays down into the black area
* so they don't cover the image.
*
* How do we do that? The naive approach would be to intercept the frame's
* draw() function and simply copy the frame's content into a larger one.
* This is quite CPU intensive because of the huge memcpy()s involved.
*
* Therefore the better idea is to trick the decoder into rendering the
* image into a frame with pre-attached black borders. This is the way:
* - when the decoder asks for a new frame, we allocate an enlarged
* frame from the original port and prepare it with black borders
* - we modify this frame's base pointers so that the decoder will only see
* the area between the black bars
* - this frame is given to the decoder, which paints its image inside
* - when the decoder draws the frame, the post plugin architecture
* will automatically restore the old pointers
* This way, the decoder (or any other post plugin up the tree) will only
* see the frame area between the black bars and by that modify the
* enlarged version directly. No need for later copying.
