In particular, device toolbar previously could be made ridiculously small.
Also in the default configuration it takes a whole line, so we now use that space in its initial size.
Mixer Toolbar initial size was a little small. Now it matches the Transport Toolbar width.
Meter Toolbar initial size was too small.
Transcription Toolbar was a little too small. Better to start out slightly wider than previously.
... for functions in final classes.
override is like const -- it's not necessary, but it helps the compiler to
catch mistakes.
There may be some overriding functions not explicitly declared virtual and I did
not identify such cases, in which I might also add override.
... 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.
It was producing "ghost" windows on OSX in wx3. These were
supposed to be hidden, but they weren't any longer and after
reviewing TipPanel, I realized that there was a separate
code path for OSX entirely...must've gone back to some of the
earliest versions.
Now all platforms use the same bit of code.
