    XCB: Don't attach uploaded surfaces as snapshots

    When you draw (part of) a surface to an XCB surface, the XCB backend will
safe
    the uploaded part as a snapshot to the input surface. This allows to re-use
this
    picture in case the same surface is later used again as a source.

    However, other backends do not do this and this has caused and/or
highlighted
    numerous bugs. Just skipping the snapshot fixes or hides these bugs.
