blendWithImage is offset x -1 with kDitherTypeBayer4x4

I tested every dither type and ONLY kDitherTypeBayer4x4 has this issue. Not even 2x2 or 8x8.

The image returned from blendWithImage is offset 1 pixel to the left.

(FWIW I did not set the phase manually.)

My full code (blending two 400x420 images):

newTimeImage:blendWithImage(oldTimeImage, transitionAnimator:currentValue(), gfx.image.kDitherTypeBayer4x4):draw(0, 0)

I have to set that to draw(1, 0) if I use that specific dither.
