+/* 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.
