This preserves the stereo-ness of files that were imported or recorded in stereo.
ToDo (maybe someday): provide a disclosure triangle that exposes the individual channels in a multichannel region
Duplicate the remove_unsued_region action in the Session->Cleanup menu, for discoverability.
Region list should use the same Region actions as the canvas...
OK, now resolve the change in use-cases of Region List and Source List. tentative.
Rough-in remove_selected_sources (Delete in Sources list).
Column tweaks.
To mitigate concurrent rendering, the waveform cache adds a random
range of pixels centered around the visible waveform.
Alignment is using integer half_width = width_samples / 2;
This always aligns the left-edge to the left-most cairo-pixel.
This fixes an issue with moving moiree patterns in waveforms when
zooming vertically (which invalidates the cache and uses a
different random number of pixels),
The left-most part may be a partial block of a given "sample per pixel"
range. Also previously there was an off-by-one [block] in case
sample_pos was an even multiple of samples_per_visual_peak.
This works around for compilers with non-static-data-member
initialization.
spinlock_t is-a struct { lockType _; } and BOOST_DETAIL_SPINLOCK_INIT
initializes the first member of the struct.
All defines of BOOST_DETAIL_SPINLOCK_INIT include c-style curly braces
to initialize the struct's data member.
However, modern C++ compiler interpret the braces differently resulting
in copy constriction of the initializer.
Depending on implementation, d8ae3fd may only construct the spinlock
once to `sl_init`. Later it is only copy-constructed and that leads to
compile and/or runtmime errors.
e.g. gcc-8.3 fails to compile
error: use of deleted function ‘boost::detail::spinlock::spinlock(const boost::detail::spinlock&)’
This fixes an issue with
* XMLNode::get_property(const char*, T&)
* XMLNode::set_property(const char*, const T&)
resulting in
string_convert.h:77: error: 'long int' is not a class,
struct, or union type
