Scales the font string's rendered text to a different height. This method scales the image of the text as already rendered at its existing height by the game's graphics engine -- producing an effect which is efficient enough for use in fast animations, but with reduced visual quality in the text. To re-render the text at a new point size, see :SetFont().
Signature:
FontString:SetTextHeight(height)
Arguments:
height- Height (point size) to which the text should be scaled (in pixels) (number)
