* presentation layer : libsvgtiny, ezxml
* render layer : twin
* output layer : uGUI
* main()
+ twin_fbdev_create() : initialize hardware
+ twin_svg_index_start() : svg parsing and drawing
- svgtiny_parse() : parse svg to drawing information
- render_path() / render_text() : call vector graphics library to finish drawing
+ twin_fbdev_activate() : first paint/update screen of hardware
+ twin_dispatch() : global loop for updating (window, screen, process input)
* manually copy svg (markup code) codes into apps/twin_svg.c via 'vim'
* parsing svg codes into drawing information for vector graphics library
* flash binary files into MCU (Micro Control Unit)
