Subject: [PATCH] Don't clamp mouse coordinates until they're fully outside the
 containing area

A window 1920x1080 pixels wide at 125% scaling will have a width and height of 1536x864, but at pixel (1919,1079) the mouse coordinate will be (1535.2,863.2), which is within the bounds of 1536x864, but larger than (1535,863).
