PouleyKetchoupp 85a934954d Implemented screen_get_usable_rect for X11 Display Server ...

Helps with fixing issues with scrolling popups not respecting screen
decorations on the display server side.

Reproduction steps for a simple use case:
- Start the editor project list
- Open the language selection popup

Support for multi-screen:
Handling decorations is supported in different ways depending on the
information the window manager provides:
- _GTK_WORKAREAS is used when available from the WM to get accurate rect
for the different screens directly (available on Gnome).
- Alternatively, strut information is used to calculate available space
for a given desktop manually (XFCE, KDE).
- As last resort _NET_WORKAREA is used. It provides one full rect for all
screens, which doesn't handle decorations on the secondary screen in all
cases.
