* Since fontchooser is replaced by selectmenu, it is no longer needed. So I rewrite it into font.lua module which can cache faces that shared among all UIs. * add progressBar method in graphics.lua to draw reading progress. * add reading progress information in reading menu. It is just a demo. Should be clean up in next release when the real reading menu is out. :)
