 Missing:
  - screen scale and size: most desktop apps expect to be in a draggable window
    on a larger desktop surface. For Android, there is usually no desktop, and
    screen resolution is often very high, so that a regular FLTK window would
    hide as a tiny gray spot in the top left corner
      * windows should probably be centered by default
      ? the screen resolution should adapt to the first opened window
      ? we should be able to hint at a prefered screen resolution
      * drawing call must scale at some point (line width!)
      * rotating the screen must call the app handler and(?) window resize
      * proportions: pixels should be square
 Need Work:
  - Fl_Android_Graphics_Driver::pie(int) needs refactoring
  - ...::line(...) has round ing issues (see rounded box type)
