render: fix ChangePicture when Xinerama is active (v2) (#49170)

Browse Source 
ChangePicture takes wire XIDs, but didn't do any Xinerama translation,
which meant setting a clip pixmap or a separate alpha picture would
result in those elements pointing at the instance of the pixmap on
screen 0.  Which is, you know, bad.

v2: This one actually builds.
