/* Looks up the MetaWindow representing the frame of the given X window.
* Used as a helper function by a bunch of the functions below.

* FIXME: The functions that use this function throw the result away
* after use. Many of these functions tend to be called in small groups,
* which results in get_window() getting called several times in succession
* with the same parameters. We should profile to see whether this wastes
* much time, and if it does we should look into a generalised
* meta_core_get_window_info() which takes a bunch of pointers to variables
