Handle warped mouse motion as floating point

Fixes certain issues where sub-pixel motions would get discarded while
the mouse is captured, such as when free look is enabled in the editor
(at least when turned on while holding right click).

Very slightly compat breaking, as actual public APIs are changed,
although with "compatible" types (Point2i->Point2).
