Add DW_FEATURE_WINDOW_PLACEMENT for platforms supporting arbitrary window placement. Several of the new platforms supported do not allow arbitrary window placement. GTK3/4 with Wayland does not allow you to specify the location, just the size. iOS and Android by default the window is the full screen, or fraction of it. GTK2/3/4 with X11, Windows, OS/2 and MacOS support arbitrary window placement.
