Add new window to allow convenient display and globally
change used color intensities for design and testing purposes.
Changes were introduced to Renderer as well as GUI service
to allow global change of used color scheme.
When using list, screen is deep refreshed each
time the color is changed.
Known issues:
Item focus borders (top,bottom) with changed black intensity
may not render properly, however it doesn't obscure the
target functionality.
Due to vfs deprecation there is need to remove all vfs calls from code. This PR covers module gui. There are some modifications in other modules included which are necessary because of build system issues.
* EGD-3585 SerwiceGUI and ServiceEink initial cleanup
* moved code to one function per message handling
* removed dead code from comments
* added Service.cpp demangling to debug messages for clear output
* added Response value to return messages to `connect()`
* Timers now are Application thread safe
* Timers now have consistent API independend of Application (no more c style timers)
* Timers can have either: callback or override onTimer() method - this
way we can create more complicated timers or just use existing ones
* gui::Timer added via adapter class GuiTimer to decouple sys::Timer
with gui::Timer
* Fixed race in wrapper
* Updated docs
* fixed using std and cpp_freertos and DataReceivedHandler hidden in Application.hpp
