You never could assume mouse coordinates were always integral. Tablets for example output non-integral mouse coordinates and have since 10.2. In Lion, hi res mice (such as Apple's trackpads and Magic Mice) will output non-integral mouse coordinates as well.

Oddly, the scrollview itself had an integral frame, and it's the scrollview's frame that I set to be non-integral accidentally, through my custom split view. The non-integral numbers comes from the mouse dragged event. I noticed this somewhere else; it seems that mouse dragged events now have fractional values in Lion.
