Mobile: Draw optimizations; focus handling

Widgets can now be marked for buffering their contents, which is useful if their contents change seldom but they are drawn often.

For example, the navbar is always visible but doesn't change very often, and during animations menu contents are static but there is a moving animation so everything gets drawn 60 FPS.

Focus handling was also improved so the lookup results can be scrolled while entering text, and one can tap outside an input field to unfocus it.
