- Fixes: when right clicking on a piano key close to the lower edge of the screen, "Mark semitone" will mark the wrong key because it uses the upper edge of the context menu as reference. - Fixes: getKey() is off by 2 pixels - Introduces: yCoordOfKey() which is the reverse of getKey() - Removes: section of code that can never be reached --------- Co-authored-by: Johannes Lorenz <1042576+JohannesLorenz@users.noreply.github.com>
