Subject: [PATCH] x11: Be a lot more careful about setting ParentRelative

We don't want to set ParentRelative when:

- the parent window is NULL
  In that case we are unsure about the depth, so better err on the side
  of caution and avoid a BadMatch by accepting ugly output.
- the cairo pattern is in an error status
  This should never happen - unless you start up in OOM - but better
  be safe than sorry.

Might help with the spurious crashes in #1280.
