_NET_WM_WINDOW_TYPE_UTILITY indicates a small persistent utility
window, such as a palette or toolbox. It is distinct from type TOOLBAR because it does not correspond to a toolbar torn off from the main application. It's distinct from type DIALOG because it isn't a transient dialog, the user will probably keep it open while they're working. Windows of this type may set the WM_TRANSIENT_FOR hint indicating the main application window.
This seems to indicate that this windows should start floating by default, as one would expect of either a "palette" or a "toolbox".
Specifically, this has implications for Picture-In-Picture windows in chromium.
