"""Game fix for Flowers - Le Volume Sur Printemps

This fix installs the font that should be bundled with the game in case it
does not get installed during the setup process. Without this fix, the default
font will be used which doesn't wrap correctly, resulting in the text breaking
outside its text box area.
