 *
 * All features from TextureNode are valid in LabelTTF
 *
 * LabelTTF objects are slow. Consider using LabelAtlas or LabelBMFont instead.
 *
 * Custom ttf file can be put in assets/ or external storage that the Application can access.
 * @code
 * LabelTTF *label1 = LabelTTF::create("alignment left", "A Damn Mess", fontSize, blockSize,
