cursor size. It should fit to the setCurrentFont function because the
cursor tells the user which font will be used when typing characters.
Especially on RTL/LTR boundaries it should fit because it is
essential for the user to see which writing direction is active. This
patch implements a simplified version of setCurrentFont's logic to
archive this.
