... Assuming that large unsigned magnitudes with high order bit set are not
the problem, but signed negatives of small magnitude may be:
1) Always cast the unsigned to signed in comparisons, not the other way.
Also:
2) Cast unsigned TERM to signed by itself, before subtracting. Don't cast
the result.
3) Rewrite some comparisons by moving subtracted term to other side.

This fixes the file truncation (missing last ~1000-2000 samples)
on file export. It will also eliminate error dialog some users
have witnessed.
Also cleans up the code
- simplified the Finalize function
- add error dialog for encoder errors
- always writes a final frame even if it has to pad with silence
- correctly determine when a codec supports short final frame
... Also checked more error returns from library functions. Detect it when
write fails (maybe because of exhaustion of space) -- don't continue,
pretending all is still well.
Using one non-specific error message in many places, because we're in string
freeze now.
... This even makes it possible to remove the prohibition of undo and redo
during transport, not that we want to though. Playback and recording will
continue, using track objects that might not be in the current project.

... and similar wx "variadics," which all treat wxString smartly enough that
you don't need this.
Don't need c_str either to convert wxString to const wxChar * because
wxString has a conversion operator that does the same.
- Dead code from experiments in SelectionBar removed.
- Many warnings about unused parameters fixed with WXUNUSED()
- Many warnings about signed / unsigned comparisons cleaned up.
- Several 'local variable declared but not used' warnings fixed.
... There are four different code paths to test, for four different "Download"
buttons:
The two "Download" buttons in the Libraries preference dialog; and,
The Download button in each of the two dialog boxes that follow the two
"Locate..." buttons.
There are just two new help pages in a proper build of local help, each the
target of two buttons.
One of these pages is called "FAQ:Installing the FFmpeg-Import-Export Library"
rather than "FAQ:Installing the FFmpeg-Import/Export Library"
because there are some difficulties preventing links to pages with "/" in the
title, which I didn't try to fix.
Previously this was hard coded to use the online alphamanual.
Some other help-on-errors paths were hardcoded to use the online manual, and did not use local help even if available, so these were changed too.
Also two naming changes in the code:
ShowHelpDialog() became ShowHelp() because it typically shows the help in your browser, only showing the help in a dialog under certain circumstances.
The helpURL parameter became helpPage since it is usually a page name that is then elaborated into a url.
The Link() function became InnerLink().
Some careful http -> https changes made too.
