XvWindowMask is defined as 0x00020000 and cannot fit in the XvAdaptor
type which is defined as an unsigned char, thus causing a compiler
warning:
xwayland-glamor-xv.c: In function ‘xwl_glamor_xv_add_adaptors’:
xwayland-glamor-xv.c:339:16: warning: large integer implicitly
truncated to unsigned type [-Woverflow]
This XvWindowMask value is actually not used for XvAdaptor itself but by
the server in its xf86xv implementation, so we don't even need that mask
in our xwayland-glamor-xv implementation.
