Windows default font glyphs are rendered wrong on some systems

[Christopher Schnick]

I'm not able to reproduce it, but some of my users are. If anyone who 
knows the font renderer maybe wants additional information or has some 
ideas on what the users can try to either fix or diagnose the root 
cause, I can relay that request to them.

I can ask them to try other JavaFX applications, but either way how that 
goes, it doesn't show the cause.
