... A call graph browser easily shows that the extra generality of fetching
samples in some other format is only used in Benchmark -- where the format is
always the same as what the track is constructed with.
This makes re-verification of the claims in comments two commits ago easier.
... without making undesirable dependency cycles.
Eliminate calls to NewWaveTrack in effects, but in Edit>Copy too, which was
not mentioned in the bug report. (Copying a track, deselecting all, and pasting
preserved CLIP colors, but not the TRACK color setting which applies to newly
generated clips.)
Instead, always use the new function WaveTrack::EmptyCopy from the track to be
later replaced, getting color information.
NewWaveTrack is still used in benchmark test, import, the Track menu
commands that make new tracks, recording to new tracks, and generators without
a selection, where there is no track to copy from.
Also when deserializing tracks from the .aup file, in which case the saved
color is later retrieved from the file.
Also, in mix-and-render, where other logic decides whether to copy colors
afterward.

... Unnecessary because transitively included.
But each .cpp file still includes its own .h file near the top to ensure
that it compiles indenendently, even if it is reincluded transitively later.
... and also fixed analogous mistakes in some effects (Vamp, SoundTouch, and
SBSMS effects), found by review of all uses of TrackList::Channels.
The first member of the pair of iterators returned by TrackList::Channels
does not necessarily deference to a null pointer when it is incremented to
the end of the range.
... except Audacity.h
This forces us to make each header contain all forward declarations or nested
headers that it requires, rather than depend on context.
... so that we can use Track::SharedPointer without undefined behavior even on
tracks that don't yet belong to any TrackList.
Also fix the return type of function template TrackList::Add and remove some
casts.
... whenever they really describe the size of a buffer that fits in memory, or
of a block file (which is never now more than a megabyte and so could be fit in
memory all at once), or a part thereof.
... A non-narrowing conversion out to long long is a necessity, but the
conversions to float and double are simply conveniences.
Conversion from floating is explicit, to avoid unintended consequences with
arithmetic operators, when later sampleCount ceases to be an alias for an
integral type.
Some conversions are not made explicit, where I expect to change the type of
the variable later to have mere size_t width.
... This makes much code agnostic about how other things (functions and
arguments) are typed.
Many of these neeed to become size_t instead of sampleCount.
These changes fix a broken build in Windows.
#include <algorithm> needed for min/max to be in std.
decltype(+name) was declaring a const variable, that could not be incremented. Changed to auto.
... I believe this list of four places is exhaustive.
There are many, many more safe narrowings that I examined.
This resulted from changing the definition of sampleCount in my builds so that
narrowing conversions failed to compile without some fixes, and I examined and
fixed every place.
The rest of that work is not yet shared.
... Should have no effect on generated code, except perhaps some slight faster
virtual function calls. Mostly useful as documentation of design intent.
Tried to mark every one of our classes that inherits from another, or is a
base for others, or has abstract virtual functions, and a few others besides.
This change is believed to be a direct refactoring that does not change functionality. It paves the way for more complex kinds of selection, such as selections involving frequency as well as time. It also reduces risk of left and right edges being swapped in future code using SelectedRegion, as the default is to swap on assignment if needed.
