title: opengl text font size
body: <p>I'm trying to show some text overlay but I need it to be bigger than size 24. the problem is I can't find a way to do that!
  At the moment I'm using:</p>
  
  <p>GLvoid *font_style = GLUT_BITMAP_TIMES_ROMAN_24;</p>
  
  <p>How can I increase the size of it? (it's no problem if I need to change to something else other than times roman)</p>
