This is mostly a simple lexical search+replace but the absence of operator< for
std::weak_ptr<T> leads to some complications, particularly with Evoral::Sequence
and ExportPortChannel.
::model_changed() is used when the model has changed (eg. new notes or some
notes deleted); ::view_changed() is used when only some view parameter (e.g.
zoom, scroll, track height etc) has been altered.
Not fully functional yet (::view_chanted() ignores scroll)

git history begins in 2005. So (C) from 1998..2005 is lost. Also some

- update_range() solely looks after visibility.
- update_note/hit() positions both x and y using code stolen from
update_range()
- add update_contents_height() for when we just change the GR height.
- find_event() is now used rather than map::find()
- use temp canvas items to avoid constructor overhead.
Currently when a GhostRegion is deleted by its "parent" RegionView it emits the
static GhostRegion::CatchDeletion signal which is connected to the
RegionView::remove_ghost method of every RegionView instance.
With a static GhostRegion::CatchDeletion signal a particular test session
causes 31 Million calls of RegionView::remove_ghost on Session deletion and the
session takes 70 seconds to close with a debug build.
The lifetime of a ghost region is tied to both the TimeAxisView(TAV) and
RegionView(RV) in that when a RegionView is deleted all GhostRegion instances
associated with the RegionView should be deleted or when a TimeAxisView is
deleted all ghost regions that are contained in the view should be deleted.
This means that there needs to be notification between GhostRegion and both
classes. Instead of using a signal for this as we know there are only two
listeners and GhostRegion already holds a reference to the TimeAxisView, also
take a reference to the parent RegionView in the GhostRegion constructor and
use it to notify the RegionView when GhostRegion destructor is called so it can
drop any references it holds.
Using a direct function call in the GhostRegion destructor to notify the
TimeAxisView and RegionView "parents" brings the unload/close time down for the
test session from 70 seconds to 4.5 seconds.
The GhostRegion also references canvas items that are added to the TimeAxisView
canvas group or at least a canvas group that it manages. So when the
TimeAxisView is destroyed and the canvas group that is the parent of those
items is destroyed, the GhostRegion's canvas items will also be
deleted/destroyed by the parent canvas item/group. This means the GhostRegions
must be destroyed when the TimeAxisView they are contained in is destroyed or
there will be dangling references to canvas items that have already been
deleted and trying to delete them again will be bad.
Remove Canvas::Layout, use Canvas::Container for the same purpose, move child-rendering into Item::render_children() so that it
could theoretically be used by any derived type.
Vimmers, try let c_space_errors = 1 in your .vimrc to highlight this kind of stuff in red. I don't know the emacs equivalent...

- Split Configuration into RCConfiguration and SessionConfiguration;
the first for options which are saved to .rc files and the second
for options which are saved in a session file.
- Move some options from the old `master' Configuration object into
SessionConfiguration; this needs more refinement.
- Reflect many RCConfiguration options in an expanded Edit->Preferences
dialog; my intention is to remove the corresponding menu items
eventually.

All #include statements that include a header that is a part of a library
bundled with ardour MUST use quotes, not angle brackets.
Do this:
#include "ardour/types.h"
NOT this:
#include <ardour/types.h>
Rationale:
This is best practice in general, to ensure we include the local version
and not the system version. That quotes mean "local" (in some sense)
and angle brackets mean "system" (in some sense) is a ubiquitous
convention and IIRC right in the C spec somewhere.
More pragmatically, this is required by (my) waf (stuff) for dependencies
to work correctly. That is:
!!! FAILURE TO DO THIS CAN RESULT IN BROKEN BUILDS !!!
Failure to comply is punishable by death by torture. :)
P.S. It's not that dramatic in all cases, but this (in combination with some
GCC flags specific to the include type) is the best way I have found to be
absolutely 100% positive the local ones are being used (and we definitely
want to be absolutely 100% positive on that one).
