Fix some issues with Steam Input glyphs reflected in upcoming Steam Client update * Glyph sizes for medium and large glyphs changed 64 => 128, 128 => 256. * Glyph style modifiers now work properly with the source files from Steam. * Added `steaminput_glyph_forceresize` cvar (default on), some of the styled glyphs are still the wrong size on Steam's end, so cvar so we know when it's safe to remove this hack. * Added `steaminput_glyph_forcetype` cvar, you can test what your game looks like with different controller types easily.
