Jules Aguillon c5f5a23d75 Fix dimensions going off after rotation
Values like 'characterSize' and 'horizontalMargin' can't be fed back into the default value because they are not of the same unit.
To avoid this happening again, change the way the default value is defined for every options.
The 'key_height' dimension was no longer used.
