I registered 'Ardour 3' as an app with Soundcloud - here are the
client_id and client_secret I got back. Probably the client_secret
shouldn't be here - I'll try to understand what should really happen and
fix this up in due course. Probably we should be using OAuth.
Also remove a couple of bits of dead code and fix a few whitespace
oddities.
Remove the Soundcloud username & password from the parameter substitutions
passed to the post-export hook: having thought about this now, I can't
actually think of a case where these are of any use at all.
In compensation, add %s and %n parameters that expand to the session
directory and name - maybe people will think of uses for these.
Items no longer need a parent group (they require a Canvas pointer instead), so all constructors have been rationalized
and have two variants, one with a parent and one with a canvas.
All Items now inherit from Fill and Outline, to banish diagonal inheritance and virtual base classes and all that.
There were zero changes to the Ardour GUI arising from these changes.
For audio: not writing frames to the capture ringbuffer offsets
the recording.
For midi: we need to keep track of the record range
and subtract the accumulated difference from the event time.
previous one, but usually ends up using three of them at the current
CACHE_HIGH_WATER setting.
Should result in a smaller memory footprint for sessions with
multiple copies of nearby audio segments (electronic style).
The downside is the larger memory footprint for linear recording
sessions if CACHE_HIGH_WATER > 1 (1 giving a max of two
half - sized cache entries per audio stream).
Constrain control points to one per tick (1/1920 beats).
Prior to this it was possible to set two values to the
same time (interpolation and iteration failed).
