There are 2 issues here:
1. When we zoom, the width and height of visibleContentsRect are not constant, and can change if we cross the integer boundaries.
2. The parent transform that is calculated in TextureMapperLayer::computeTransformsRecursive has a rounding error.
I have a patch that needs some cleanup. I will upload it once it is ready.
