Property DisplayWindowDescription.is_topmost() does not work on Mac OS

[kapulkin]

The code below creates window, which is not always on top

`

// Set the window description
clan::DisplayWindowDescription desc_window;
desc_window.set_title("Motion Learning");
desc_window.set_topmost();
desc_window.set_popup_window();
desc_window.set_allow_resize(false);
desc_window.set_layered(true);
desc_window.show_caption(false);
desc_window.set_size(clan::Size(1792, 828), false);

// Open the windows
window = clan::DisplayWindow(desc_window);

`

There is a discussion on Stackoverflow, how to implement the topmost feature for X11: https://stackoverflow.com/questions/4345224/x11-xlib-window-always-on-top

Unfortunately, currently no developers are working on the MacOS at the moment
