/* General information function about the given window. Pass in a sequence of
* pairs of MetaCoreGetTypes and pointers to variables; the variables will be
* filled with the requested values. End the list with META_CORE_GET_END.
* For example:
*
* meta_core_get (my_display, my_window,
* META_CORE_GET_X, &x,
* META_CORE_GET_Y, &y,
* META_CORE_GET_END);
*
* If the window doesn't have a frame, this will raise a meta_bug. To suppress
* this behaviour, ask META_CORE_WINDOW_HAS_FRAME as the *first* question in
* the list. If the window has no frame, the answer to this question will be
* False, and anything else you asked will be undefined. Otherwise, the answer
* will be True. The answer will necessarily be True if you ask the question
* in any other position. The positions of all other questions don't matter.
*
* The reason for this function is that some parts of the program don't know
* about MetaWindows. But they *can* see core.h. So we used to have a whole
* load of functions which took a display and an X window, looked up the
* relevant MetaWindow, and returned information about it. The trouble with
* that is that looking up the MetaWindow is a nontrivial operation, and
* consolidating the calls in this way makes (for example) frame exposes
* 33% faster, according to valgrind.
*
* This function would perhaps be slightly better if the questions were
* represented by pointers, perhaps gchar*s, because then we could take
* advantage of gcc's automatic sentinel checking. On the other hand, this
* immediately suggests string comparison, and that's slow.
*
* Another possible improvement is that core.h still has a bunch of
* functions which can't be described by the formula "give a display and
* an X window, get a single value" (meta_core_user_move, for example), but
* which could theoretically be handled by this function if we relaxed the
* requirement that all questions should have exactly one argument.
