The FPS in the viewport is displayed in a string of the form "fps:
%.2f". The string that stores it is of length 16, which is plenty
enough in English. But the translated message in Hindi uses
Devanagari, which takes up 4 bytes per char. Because of this, it is
too long and there is not enough room for the numbers to actually
appear.
To solve this, the containing string length was doubled to 32 chars.
