A list of "user applications" is built at compile time. It contains all the info needed to create the application at runtime (ptr to a create() function) and to display the app in the application menu. All applications declare a TypeTrait with these information.
When a new app must be loaded, DisplayApp first check if this app is a System app (in which case it creates it like it did before). If it's not a System app, it looks for the app in the list of User applications and creates it if it found it.
Those changes allow to more easily add new app and to select which app must be built into the firmware.
Switch to C++20 (and fix a few issues in SpiMaster.cpp and Watchdog.cpp.
Navigation app now needs 2 images to be loaded from the resources on the external filesystem. This PR adds an 'enabled' field to the Applications struct. This field is true for all applications expect for Navigation which calls Navigation::IsAvailable(). This methods returns true if the 2 files are available in the resources.
The application list disables the application (draws it in grey, disables the touch callback) if the enable flag is not set.
The DisplayApp class isn't used in the Screen base class and most
screens, so requiring it is pointless.
In this commit, DisplayApp pointers were added to screens which use it
and the explicit Screen constructor was removed in those screens.
When the screen switches, the full screen needs to be refreshed for the
hardware scrolling to work. This was enforced with backgroundLabels, but
is simpler to do with a rounder function.
There is a large step in brightness from level zero to level one.
After experimenting with various ST7789 options, I found that
decreasing VDV to 0x10 (-0.4V) fixes this issue.
The gamma change reduced the average error in brightness, but with the
underlying issue fixed, the gamma change has been reverted.
Don't use relative imports like `../foo.h` as those depend on the
relative position of both files. Rather than that use imports relative
to the `src` directory, which explicitly is part of the include
directories.
