reset webTextView size if focus bounds changes

When the focus bounds is changed by webkit, reflect that
change on the UI side in the WebTextView. On the WebCore
side, add the focus-changed state to the Draw record,
which is sent whenever a new picture is recorded.

On the WebView side, set a bit when receiving the Draw
record, and check that bit when the picture is first drawn.
This additional delay is required so that the bit isn't
checked until after the new nav cache is swapped in.

If the bit is set when the draw occurs, clear it, and
set up the WebTextView's bounds.
