// A Font object can be one of three states
// NF_FONT_COMPLETE
// The font object is complete and usable in this state. All normal
// fonts (not webfonts) are in this state always. Once in this state,
// the font object will never switch its state back to any of the
// other states.
// NF_FONT_INCOMPLETE
// A font object will assume this state if there is the font data
// is BEING DOWNLOADED. This state will happen only for webfonts.
// Users of this font object, will need to wait until the state
// switches to NF_FONT_COMPLETE to use the font object.
// NF_FONT_ERROR
// If downloading a font was interrupted or was in error, then the
// font object takes this state. Users of the font are expected to
// release the font and take appropriate measures to react to
// the requested font not being available.
