Get OSD (on-screen display) width/height without actually rendering

[r0n]

Is it possible to get the OSD width/height without actually rendering it?
I want to use the retrieved widht/height to adjust the X/Y position in the actual code that renders the OSD.


I can imagine you might need to modify the original "OnScreenDisplay" function, this might take a lot of time.
So this is not an urgent request, but maybe there is another way around or something?
