Develop
=======
Change
------
SystemTrayIconComponent::setIconImage now takes two arguments, rather than one.
The new argument is a template image for use on macOS where all non-transparent
regions will render in a monochrome colour determined dynamically by the
operating system.
Possible Issues
---------------
You will now need to provide two images to display a SystemTrayIconComponent
and the SystemTrayIconComponent will have a different appearance on macOS.
Workaround
----------
If you are not targeting macOS then you can provide an empty image, `{}`, for
the second argument. If you are targeting macOS then you will likely need to
design a new monochrome icon.
Rationale
---------
The introduction of "Dark Mode" in macOS 10.14 means that menu bar icons must
support several different colours and highlight modes to retain the same
appearance as the native Apple icons. Doing this correctly without delegating
the behaviour to the operating system is extremely cumbersome, and the APIs we
were previously using to interact with menu bar items have been deprecated.
Change
------
The AudioBlock class now differentiates between const and non-const data.
