How would that work?  the MouseEvent merely provides the cursor position, If
the OS does not provide floating point positions for a mouse -- if the
coordinates were fractional that would imply that the cursor could have a
position between pixels, which would be useless as (by definition) the user
would not be able to distinguish the actual position.

Drawing programs should be maintaining a current view scale, and the inverse
should be applied to any mouse actions performed on the current drawing surface
(eg. <canvas>) to find the position of a mouse event in the scaled surface.
