Android input method improvements

Use the new inputmethod query API. and get rid of the hack where
we would move the cursor back and forwards to make sure that the
Android software keyboard noticed that the cursor had moved.

The android plugin now uses absolute positions instead of
position within the paragraph for all cursor handling (provided
that the control supports the new API).

X11: defaultDragDistance depends on screen resolution

The usual default is 10 pixels, but on a screen with resolution
exceeding 100 DPI, it will be a proportionally larger number.  The
reason is that such precise finger and mouse movements are more
difficult on higher-resolution screens.
