SDL/src/video/wayland/SDL_waylandwindow.h
Frank Praznik e482904111 Add support for non-constrained and non-grabbing popups 
By default, popups are automatically constrained to be completely within display bounds, so as not to cut off information and result in an unusable menu, or unreadable tooltip. In some cases, however, this is not wanted, so a property to toggle this behavior is added.

There are also cases where the client may not want a popup menu to implicitly grab the keyboard focus, as is the default behavior, so popup menus now respect the focusable flag/property, as well as being able to toggle focus grabbing via SDL_SetWindowFocusable().

(cherry picked from commit b871ac0d97)
