title: gdx-freetype is slow to generate fonts
body: <p>I'm currently using the gdx-freetype library to generate the BitmapFonts for my game. It's really convenient since I can use it to handle the different screen sizes on Android. The problem is that it takes a long time for a font to be made. At startup I generate some BitmapFonts in a few different sizes (from the same .ttf file), so the time spent generating fonts, adds to my loading time. This is a problem, since it can easily take 5-6 seconds to generate the fonts.</p>
  
  <p>Is there anything I can do to speed up the process or should I try some alternative to gdx-freetype? Perhaps I'm approaching this problem in a wrong way?</p>
