Kludgey fix for invisible playhead when scrolled.
...
The problem this is avoiding makes absolutely no sense. Either I'm dumb, or
something is more deeply wrong with scroll group bounding boxes, or both, but I
don't care anymore. This works. Viva release mode.

Put playhead on top of everything.
...
Achieve this by adding a new hscroll group just for cursors.
That requires a slightly smarter window_to_canvas() to deal with overlapping
sensitive scroll groups. New rule is that scroll groups can overlap, but the
most sensitive one found from the top down will be chosen to translate
coordinates. This basically means don't overlap scroll groups with different
sensitivities.
In the presence of scroll groups, having a canvas-wide window_to_canvas()
and/or canvas_to_window() fundamentally makes no sense. At some point in the
glorious future we should kill those and use only item-relative coordinate
translation.

Fix mouse event position offset bug.
...
Search scroll groups for event delivery from top to bottom rather than bottom
to top. Overlapping scroll groups still aren't properly supported by the
canvas, but currently all we care about is that the top one gets the event, so
the hscroll group (tempo lines) can be below the hvscroll group (tracks), but
the latter gets events.

change Item::visible() to Item::self_visible(); add Item::visible() which returns accurate visibility
...
Child items will be hidden when their ancestors are hidden. The old ::visible() implementation didn't reflect this. In addition,
when changes are made to hidden items (new definition of visible/not visible), don't bother to request redraws, since this will
be done when the item becomes visible again.

either way, canvas should eventually switch to
