// Special clamping used in the encoder when calculating a prediction
//
// Logically, all pixel fetches used for prediction are clamped against the
// edges of the frame. But doing this directly is slow, so instead we allocate
// a finite border around the frame and fill it with copies of the outermost
// pixels.
//
// Since this border is finite, we need to clamp the motion vector before
// prediction in order to avoid out-of-bounds reads. At the same time, this
// clamp must not change the prediction result.
//
// We can balance both of these concerns by calculating how far we would have
// to go in each direction before the extended prediction region (the current
// block + AOM_INTERP_EXTEND many pixels around the block) would be mapped
// so that it touches the frame only at one row or column. This is a special
// point because any more extreme MV will always lead to the same prediction.
// So it is safe to clamp at that point.
//
// In the worst case, this requires a border of
// max_block_width + 2*AOM_INTERP_EXTEND = 128 + 2*4 = 136 pixels
// around the frame edges.
