837a96d18a Scrub queue records positions as sampleCount not long 2016-09-04 16:28:40 -04:00

954a914ff7 A little more type agnosticism 2016-08-26 12:42:22 -04:00

79c79f9cd3 Remove many mentions of sampleCount with auto and decltype... 
... 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.

18eb2bbc7a Bug 193 - Audacity can't record at > 16-bit under MME or Windows DirectSound 
Fix by Uwe and Carsten of DirectSound issue (only).  We can't interrogate for formats, so we use userData to tell PortAudio what the format should be.  I have a 16 bit built in sound device and that continues to function correctly at 16 bit with 24 bit requested.  Unable to test on a 24 bit device.

9a256d3790 Don't let the consumers discard too much from the scrub queue... 
Producer adds silences when needed, so that the accounting in Transformer()

b6764d1bf7 Reduce scrub lag yet more, at expense of possible skips in play... 
by discarding work from the queue sometimes on the consumer side.

Also more careful mixed long - double arithmetic.

19ef2f6681 Implement drag-scrub, compatibly with the existing move-scrub... 
... Start scrub by click or double click on the scrub head; release button or
not; then move.

If you release before moving, you get scrubbing as before, controlled by
motion.  Click or drag to switch in and out of seeking.  Stop with ESC,
spacebar, etc.  No change of selection.

But now if you drag, then scrubbing contines until you release the mouse or
otherwise stop with a key.

If by release of the mouse, then the selection changes as if by a click at
the last play position.  If you hold shift, then, as if by shift-click.

If drag begins with a double-click, then the play head remains centered and
the track moves.

7824e94030 Harmlessly qualify classes as final (or explicitly comment not)... 
... 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.
