/**
* A method to request that this provider provide a window. The window
* returned need not to have the right name or parent set on it; setting
* those is the caller's responsibility. The provider can always return null
* to have the caller create a brand-new window.
*
* @param aParent Must not be null. This is the window that the caller wants
* to use as the parent for the new window. Generally,
* nsIWindowProvider implementors can expect to be somehow
* related to aParent; the relationship may depend on the
* nsIWindowProvider implementation.
* @param aChromeFlags The chrome flags the caller will use to create a new
* window if this provider returns null. See
* nsIWebBrowserChrome for the possible values of this
* field.
* @param aPositionSpecified Whether the attempt to create a window is trying
* to specify a position for the new window.
* @param aSizeSpecified Whether the attempt to create a window is trying to
* specify a size for the new window.
* @param aURI The URI to be loaded in the new window. The nsIWindowProvider
* implementation MUST NOT load this URI in the window it
* returns. This URI is provided solely to help the
* nsIWindowProvider implementation make decisions; the caller
* will handle loading the URI in the window returned if
* provideWindow returns a window. Note that the URI may be null
* if the load cannot be represented by a single URI (e.g. if
* the load has extra load flags, POST data, etc).
* @param aName The name of the window being opened. Setting the name on the
* return value of provideWindow will be handled by the caller;
* aName is provided solely to help the nsIWindowProvider
* implementation make decisions.
* @param aFeatures The feature string for the window being opened. This may
* be empty. The nsIWindowProvider implementation is
* allowed to apply the feature string to the window it
* returns in any way it sees fit. See the nsIWindowWatcher
* interface for details on feature strings.
* @param aWindowIsNew [out] Whether the window being returned was just
* created by the window provider implementation.
* This can be used by callers to keep track of which
* windows were opened by the user as opposed to
* being opened programmatically. This should be set
* to false if the window being returned existed
* before the provideWindow() call. The value of this
* out parameter is meaningless if provideWindow()
* returns null.
* @return A window the caller should use or null if the caller should just
* create a new window. The returned window may be newly opened by
* the nsIWindowProvider implementation or may be a window that
* already existed.
*
* @see nsIWindowWatcher for more information on aFeatures.
* @see nsIWebBrowserChrome for more information on aChromeFlags.
