It combines the old IdentInterface with the ParamsInterface, providing an identifier and parameters (if needed).
The main purpose of the change is to make the class hierarchy (as viewed via doxygen) much easier to follow.
... Remove mention of obsolete plans for TrackPanel refactor, superseded by a
different refactor now accomplished.
Remove detailed mention of names of functions and data members that implement
drawing.
Move most of Roger's comments about drawing into Overlay.h which is now the
more relevant place.
Commented more correctly what TrackPanelListener is.
Problem: profiled the limiter effect, and found that wxGetLocalTimeMillis() in ProgressDilaog::Update was taking up a lot of time.
The slow down of the nyquist effects and analysers was introduced by the switch to wxWidgets 3.1.1, so presumably there was some change to the implementation of wxGetLocalTimeMillis()
Fix: Use wxGetUTCTimeMillis() instead of wxLocalTimeMillis() in ProgressDialog.cpp. This is much faster on Windows, and wxWidgets recommend its use to due wxGetLocalTimeMillis() being affected by start/end summer time (daylight saving time).
... not the negation of max(), which is wrong for unsigned types, and not
min(), which gives least normalized positive value for floating point types.
lowest() wasn't available before C++11.
... This was motivated by punch and roll recording: it appears most convenient
to pin the head for recording purposes, and drag it near the right, but when
stopping and finding the splice point for the correction, it is better to
scrub unpinned.
Now we show "11:07:29 +" for a time 100 years, 11 hours, 7 mins and 29 seconds in the future, rather than ASSERTing.
The + should probably be mentioned in the manual. "In the countdown, times more than 24 hours ahead aren't shown fully. A '+' sign after the time indicates that it is more than a day ahead."
... also make popup menus at right up, not down, for consistency with other
popup menus in TrackPanel
Base class also does the event propagation "hack" for ScrubPoller
... All updates of position are done in DoGetRectangle(). Ruler need only
expose one function, DrawOverlays().
Don't redraw indicators twice when dragging (hiding and showing again), making
some flicker. Just do one update.
All backing bitmaps (not just the one in track panel) now are set to 24 bits.
Big thanks to David Bailes for tracking down the root cause of slow BitBlts, and the comments at https://trac.wxwidgets.org/ticket/14403 which led to the fix.
In testing the bitmaps, I also fixed the sizer errors reported for Export.cpp that wxWidgets now reports as ASSERTS when running in debug builds.
