GTK_WINDOW_DIALOG by default allow_grow?

[Antonio Campos <acampos ceronet com>]

Just a thought:

I think that GTK_WINDOW_DIALOG windows, should default to
allow_grow=FALSE when created, because they are usually used to display
temporary and fixed sized information on the user screen. (I think
GNOME dialogs work this way).
If for whatever reason, a programmer wants an GTK_WINDOW_DIALOG allowed
to grow (allow_grow=TRUE) (I think it's not a good idea, see what ugly
looks the GIMP Tip of The Day dialog when maximized...), she/he allways
has the opportunity to do it through a call to gtk_window_set_policy ...

Another thing related to resizing... I would like to see a WM able to
hide the resize cursors that appear when you are on the corners of a
window, if this window has allow_grow and allow_shrink equal to FALSE.
This is good from the user perspective, since the user notes that the
window can't be grown or shrunk. And I obviously think this is the right
thing for GTK_WINDOW_DIALOGs too.
Is this a GDK/GTK related problem or a WM one?
