1050 *
1051 * If one plots the dst axis vertically, the src axis horizontally, then a
1052 * 1-d stretch/shrink is rather like finding the pixels to draw a straight
1053 * line. Following a Bresenham type argument from point (s_i, d_i) we must
1054 * pick either (s_i + 1, d_i) or (s_i + 1, d_i + 1), however the choice
1055 * depends on where the centre of the next pixel is, ie whether the
1056 * point (s_i + 3/2, d_i + 1) (the mid-point between the two centres)
1057 * lies above or below the idea line. The differences in error between
1058 * both choices and the current pixel is the same as per Bresenham,
1059 * the only difference is the error between the zeroth and first pixel.
1060 * This is now 3 dy - 2 dx (cf 2 dy - dx for the line case).
1061 *
1062 * Here we use the Bresenham line clipper to provide the start and end points
1063 * and add the additional dy - dx error term by passing this as the bias.
