[PATCH] winex11.drv: Use Unsorted instead of YXBanded in Xlib calls that may use multiple rectangles.

[Zhiyi Zhang]

There is no guarantees in Wine to make sure the rectangles passed to Xlib calls fit the
requirement of using YXBanded. See 'man 3 XSetClipRectangles' for details of YXBanded.

Fix a bug that OCTOPATH TRAVELER may crash with BadMatch X errors when changing resolutions in
fullscreen mode.

GDI regions are supposed to be YXBanded. If there's a place where that's
not true it's a bug.
