Datagrid: multiple hilites

[David Bovill]

I checked again Trevor. It makes sense that it does not work in cases where
the controls are not cached - where it is broken is when the controls are
cached but you try to get:

the dgRectOfIndex [1] of dataGrid

and the controls are scrolled heavily, so that the invisible row view would
be above the top of the card. In these cases it does not return the correct
geometry as the invisible row view is limited to the top of the screen and
no its "true" negative y values. These means that if you try to scroll to
the first row it does not work.
