[PATCH] Cygwin/X: Fix glxWinCreateDrawable() for API change

[Colin Harrison]

Hi,

I've had to use these changes myself since commit
9de0e31746d5f0d9d39d11c94ec3cbc04a9935fc (dri2: Take an XID for tracking the
DRI2 drawable, 11 May 2010),
so am very happy to add 'Tested-by' and 'Reviewed-by' to Jon's patch.

Thanks,
Colin Harrison
