/*
    Apple does not provide for a bitmap font except with respect to glutBitmapFont
    glutBitmapFont does not provide many different fonts
    To compete with windows programs, we may want to use bitmap fonts, but with the above, we are limited
    Therefore, we create glBitmapFont
    glBitmapFont handles writing text to the open gl context
    glBitmapFont will create a Bitmap font with any font you can name as a font 
        as long as it can be used in both NSFont and CGContext
