High DPI support

The template app supports high DPI displays out-of-the-box. The header src/core/Core/DPIHandler.hpp defines the interface for DPI handling. The implementations are in src/core/Platform under DPIHandler.cpp per platform.

The following two functions are important for DPI handling.

get_scale()

Returns a float scaling factor used to set render and font scale. Should be used whenever a relative scaling is needed. See usage in platform DPIhandler.cpp files and src/core/Core/Application.cpp, run method.

get_dpi_aware_window_size()

Returns a WindowSize, a struct with height and width as int. Will scale Window::Settings DPI aware per platform. See file src/core/Core/Window.cpp.
