* pick either (s_i + 1, d_i) or (s_i + 1, d_i + 1), however the choice
* depends on where the centre of the next pixel is, ie whether the
* point (s_i + 3/2, d_i + 1) (the mid-point between the two centres)
* lies above or below the idea line. The differences in error between
* both choices and the current pixel is the same as per Bresenham,
* the only difference is the error between the zeroth and first pixel.
* This is now 3 dy - 2 dx (cf 2 dy - dx for the line case).
*
* Here we use the Bresenham line clipper to provide the start and end points
* and add the additional dy - dx error term by passing this as the bias.
