Path to a TrueType font file to use to draw text.
Size of the texture to store font glyphs in. The actual texture size is a square of this value.
A bigger texture allows to draw more Unicode characters (if the font supports them). 256 (62.5kiB) should be enough for ASCII, 1024 (1MB) should be enough for most European scripts.
True on success, false on failure.
