MetaWindowActor: Freeze shouldn't affect actor position

Browse Source 
If a window is frozen because it is repainting, that shouldn't kee[p
us from updating its position: we don't want a slow-to-update window
to move around the screen chunkily when dragged. (This does reduce
the efficiency of begin/end frames for replacing double-buffering,
but that never works very well in the case where there was an overlapping
window or the entire screen needed redrawing for whatever reason.)

This fixes a bug where a window that was mapped frozen would not get
positioned properly until after the map effect finished, and would
jump from 0,0 at that point. Since effects *do* need to prevent
actor repositioning by Mutter, we must position the actor before any
effect starts.

Because we now are queuing invalidates on frozen windows, fix the
logic for that so that we properly update everything when the window
unfreezes.
