(moved to tracker) SetGameOption (upscale fonts)

[Radiant]

I would like to modify the option "fonts designed for 640x480" ("don't scale up fonts" in earlier versions) at runtime. From earlier conversation, I believe that SetGameOption() should be able to do that, although the parameter required for that is not defined nor listed in the manual; so instead of SetGameOption(GO_UPSCALE,1) I'd have to use SetGameOption(9999,1) where 9999 is some number. Can someone tell me how to do this please?

Some of the options cannot be used at runtime, that is simply not supported ATM, because some things are initialized only at startup.
The option number is 16, but it won't work normally in current version.
