... 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.
... 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.
This fixes the first of two related memory leak bugs:
New project. Make a new track. Select the track and use any generator, such
as white noise, specifying a long enough length that a progress dialog appears.
Cancel the progress dialog.
Save the project. Exit and restart Audacity. Reopen the project.
Orphans!
