A patch to add support for XRandA 1.2. It will break many things.

Wine currently supports XRandR 1.1, which is fine for single-monitor users. It
is bad for multi-monitor users because every time wine tries to change the
resolution it completely mucks everything up, and usually switches off a
monitor, eg, bug 16958 (which is a XRandR problem).

XRandR 1.2 introduced some very major architecture changes (*) to support
multi-monitor setups.

I've attached a badly formatted & crufty patch that implements the required
bits of XRandR 1.2. Some issues remain:

A) Fullscreen applications no longer occupy the whole X Screen - only one
physical screen. Games will need to confine the mouse pointer to that screen to
remain playable, and I don't know where in Wine to do this. This may run afoul
of bug 6971.

B) I'm not certain how this patch might interact with DirectDraw & Direct3D -
it probably breaks the screen co-ordinate assumptions in wine.

I don't think it is worth tidying this patch to the formatting standard
required for Wine until A is dealt with.

The patch includes a lot of garbage included as I tried to work out how ddraw
and xrandr interacted (sorry), and what Xinerama was doing in the mix. The
really important parts are X11DRV_XRandR_Init(void), make_modes(void), int
X11DRV_XRandR_GetCurrentMode(void) and LONG X11DRV_XRandR_SetCurrentMode(int
mode) in xrandr12.c.

Sec. 1.2 - wine should be resizing crtc, not the screen.
