Merge lp:~3v1n0/unity/panelmenu-fixes into lp:unity

[Marco Trevisan (Treviño)]

Fixed lots of other PanelMenuView related bugs (see the linked list of "In Progress bugs" for reference).

In particular, I've also changed these things:
 - Moving to nux::GetGraphicsDisplay()->GetMouseScreenCoord() (instead of gdk functions,
   warning this needs nux bzr-453 or newer not to crash, thanks to Jay for fixing!)
 - Checking for mouse position after closing menus to hide/show them (bug bug #843670)
 - Checking for mouse position after dragging a window to to hide/show menus
 - Fix for PluginAdapter not to consider unmapped windows as maximized (bug #781215)
 - Panel-service: correctly close menus when releasing mouse outside a menu title (bug #844309)
 - Panel-service: cache the indicator entries geometry and use the values for checking mouse position
 - Don't redecorate windows on maximization drag (bug #838923)
 - panel-service: Remove id2entry_hash and use sscanf to parse the entries IDs
 - PanelView: track mouse position only when it has been changed (fix bug #834065)
 - PanelMenuView / PanelIndicatorsView: remove code duplication for adding an entry
 - Better mouse grab management using only PanelTitleGrabArea
 - PanelMenuView: even more checks to avoid to show/hide menus when we shouldn't
 - PanelView: sync geometries for real

See the related commit logs for more informations.

This branch, to work properly, needs the updated UnityCore code that I've pushed in my lp:~3v1n0/unity/menus-switching-hacks branch (for the entries geometry things), so in the case that the other branch isn't accepted, we need to port its UnityCore changes here.

PS: for the record, this is the previous merge request for this branch: https://code.launchpad.net/~3v1n0/unity/panelmenu-fixes/+merge/73622

[Jason Smith (jassmith)]

Has a merge conflict if you merge your other branch in first. Conflicts are non-trivial (at least for me to fix)

review: Needs Fixing

[Gord Allott (gordallott)]

looks okay from here +1
