Support form controls that may need incremental redraw
https://bugs.webkit.org/show_bug.cgi?id=130736
Reviewed by Beth Dakin.
There are some form controls that change appearance
over time. Expand the ControlStates so that it can
hold a little more information, including a reference
to the native form control. This way the Theme implementation
can repaint the existing native control if necessary. At
least ThemeMac was reusing a single control for painting
all instances before this change.
Since ControlStates is now a class, pass it around by
reference.
The other major change is keeping a timer to trigger a
repaint in RenderBox, which happens if Theme/RenderTheme
update the ControlState to request one.
