Also integrated a basic the tracker Effect with the UI, changed the effect creation to use Json messages, and added the ProcessingController class to handle thread communication
Previously, x0.98 gain was applied for all input audio sources. As it's
no longer needed, the new values should be specified as reference for
the tests.
The same old variables will be respected for setting the path, but the
PREFERRED method is defining `-DUnitTest++_ROOT=/path/to` on the
CMake command line. _ROOT variables are handled with extra intelligence
by CMake.
The find module will also attempt to locate the pkg-config file
UnitTest++.pc, and if found will import its data.
- A new CMake option, ENABLE_TESTS, is created and defaults ON
(Legacy -DDISABLE_TESTS=1 on the command line will override)
- Target info for docs and tests is shown in the FeatureSummary
- The new ordering (with the frame rate AFTER width and height) doesn't
match the other signature, but it *is* consistent with the Timeline
constructor, and it just feels more natural
- Added overloaded-function notes to doxygen strings in FFmpegWriter.h
- Also added a warning about the argument order mismatch above
