[Ted Gould <ted@xxxxxxxx>]

Ted Gould has proposed merging lp:~ted/dbusmenu/glob-layout-updates into lp:dbusmenu with lp:~ted/dbusmenu/glob-property-requests as a prerequisite.

Requested reviews:
  DBus Menu Team (dbusmenu-team)


This branch makes it so that layout updates are sent once every visit to the idle loop.  So sets of updates are pulled together to a single signal.
