Thierry Crozat 3dee5bb762 AGS: Script API: add "restrictToViewport" arg to Screen.ScreenToRoomPoint()
This argument works similarily to Viewport.ScreenToRoomPoint():
if it's set to true then the function returns null if there's no
viewport under the cursor; if it's set to false it converts
coordinates through the primary viewport in such case.
