- 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)
-  - grab() not working when leaving window (adjuster...)
-  - scrolling if implemented as a complete redraw. Must implement real scrolling
-  - the 'hotspot' idea to position dialogs under the mouse cursor makes little sense on touch screen devices
-  - fix screen when keyboard pops up in front of the text cursor or input field (temporarily shift up?)
-  - ending 'message' will not quit the app right away, but wait for some timeout
-  - no support for dead-key entry
-  - no Shift-Tab
