Make use of frame-independent window configurations

[wasamasa]

Now that window configurations are no longer bound to frames, a new set of possibilities opens up. There is no more need for storing them in frame-local variables. Asides from that, the behaviour per frame could be tuned on a fine basis. For example, the list of window configurations could be global and the currently selected one frame-local. Other things to think of would be commands taking frames into account, such as throwing a window configuration from one frame to another one.

Does this mean I can have one global set of window configurations and share those between all the frames? Create a view on frame1 and then apply it on frame2?

[wasamasa]

Yes. Previously applying a window configuration to a different frame than it was created from did fail, now this is possible to do, as long as both frames are of the textual or graphical type.
