I've removed the WmWindowMus overrides, so this ends up using the WmWindowAura code, which calls to window_util. window_util up setting the window property kSnapChildrenToPixelBoundary and calling ui::SnapLayerToPhysicalPixelBoundary to adjust the layer. This may be ok to leave in ash as only ash calls SetSnapsChildrenToPhysicalPixelBoundary.

Sadrul/Fady, are the calls to ui::SnapLayerToPhysicalPixelBoundary ok to have only in ash? The code should only be calling this for layers created in ash, but they may be embed points.

As ash handles the layout of everything this is no longer applicable.
