We've long had double precision mouse coordinates on wayland (e.g. when rotating a window) but with the new scaling we even have it on X (and, its also in Xinput2), so convert all the internal mouse/device position getters to use doubles and add new accessors for the public APIs that take doubles instead of ints.
