Added implementation for case target_sbc == 0. In that case, the function shall schedule a wait until all pending swaps for the drawable have completed. Fix for non-blocking case. Old implementation returned random, uninitialized values for (ust,msc,sbc) if it returned immediately without scheduling a wait due to sbc >= target_sbc. Now if function doesn't schedule a wait, but returns immediately, it returns the (ust,msc,sbc) of the most recently completed swap, i.e., the UST and MSC corresponding to the time when the returned current SBC was reached.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
