Arguments: window
Returns true if the specified window is allowed to have child windows.
If is-child-allowed returns nil for a window
foo, and a second window bar is created with the foo specified as its
parent, then bar becomes an owned window of foo rather than a child
window.
This feature is used by the IDE's development-main-window to force all windows created on it to be owned. In addition, the default parent of a window created in the IDE is the development-main-window. Because of these two facts, a window created in the IDE with no parent specified becomes an owned window of the IDE's invisible development-main-window.
An application could add an is-child-allowed method for a class of window that is intended to always be an owner window rather than a parent.
