This fixes a design error of using zero as the flag for an "Immediate" event's action frame. Zero
is a perfectly legitimate action frame for an event (e.g. a Skip event), and using zero was causing
skip events with action-frame == 0 to be treated as immediate, not scheduled.
This is a little hard-edged in that edits while rolling will prematurely chop
off any playing notes, but at least the state of things actually reflects
reality. More sophisticated solution hopefully to come...
This shouldn't be necessary: Mixbus should probably just have a different
value for the default in their source tree instead.
This (partially) reverts commit 631467f0bb:
I now realise that I accidentally rolled another fix (missing "region-" in
config variable name) in there too: sorry about that.
Mixbus prefers that both the newly-created regions as well as the existing
selection are selected after splitting selected regions: make this the
default on Mixbus.
Add a configuration variable to choose the behaviour of the region
selection after splitting selected regions.
Add options to choose between all eight possible combinations of 'existing
unmodified selected regions', 'newly-created regions to left of split',
and 'newly-created regions to right of split', but comment out all but the
three least crazy ones for now. If anyone wants them, they're there.
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.
Unfortunately we store the state of models as simply model, so if there's ever
duplicate model names, we're somewhat screwed, but this makes the (previously
unmanageably huge) menu usable, while retaining the "model name as global
identifier" state unmodified.
This was a very clever attempt to fix a non-problem. If the platform doesn't have enough file descriptors available
then the platform is broken and we're not going to hack around trying to fix it.
