Also run it across the whole tree to get everything using the One True Style.
We don't yet run this in an automated fashion as it's a little slow, but
there is a snippet to do so in makeall.sh.
Don't crash when updating menu item that's not in the window server. Menu Items begin with an invalid ID of -1, and only get a valid ID if the menu they are attached to is added to the window server. They don't send updates to the server unless they have a valid ID.
Fixes#82
Now GTextEditor manages its own editing actions (cut/copy/paste/etc) and
will show a context menu containing them when requested.
Apps that want to put a GTextEditor's actions in its menu can get to the
actions via public getters. :^)
GMenu now has an "on_item_activation" callback that fires whenever one
of its items are activated. The menu item identifier is used to distinguish
between items.
Use this to implement font switching in Terminal. :^)
