/* 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.
