Bug: loading and saving a note without moving it could change the note's
position. Moving a note with the keyboard could also cause unintended
changes to the note's size or position. This was because of floating
point errors when converting from percentage coordinates (floats) to pixel
coordinates (integers).
Fix: store note coordinates as pixel coordinates instead of as
percentage coordinates. Percentages are only used to position notes for
display.
Also fix it so you can resize rotated notes with the keyboard. This was
disabled before.
