How do you find the center pixel?
Say I have the width set at an even number of pixels, 8.
Pixels going across pizel 0, pixel 1... to pixel 7.
I would think initially that to get to the centre, you'd say (8-1)/2 but this would be 3.5, and there's no pixel 3.5, so how would processing resolve this? Round up to pixel 4? And settle for an off-centre pixel?
Or should I say 8/4, instead of minusing 1 for the zero that gets counted?
