* wire hud_fontscale so HUD font scaling can be used independently from
hud_scale
* allow small optimizatinons, like optional UTF-8 decoding, or not calling
SetRenderMode for each character
* even less copypasted code in text drawing between client code and console
* get rid of direct DrawCharacter calls when it can be just DrawString
* fix net_speeds, r_speeds with scaled console fonts
* try to fix MobilityAPI's pfnDrawCharacterScaled
* center keyboard keys in OSK code
