Dear Maintainer,

The attached document displays well in windowed mode and in full
screen, EXCEPT when the full screen happens inside a Xephyr window.
All other pictures of the document were displayed fine (including
within xephyr).

Best,
C.

This is not related to zephyr, but the image in this document sometimes
disappears based on zooom levels.  You can see it by running:

    pdftocairo -r 100 -singlefile -png -f 1 -l 1 D.pdf a
vs.
    pdftocairo -r 150 -singlefile -png -f 1 -l 1 D.pdf a

The PDF contains drawing commands with large numbers like:

    0 0 m
    0 2147483647 l
    1098 2147483647 l
    1098 0 l
    W* n

And cairo doesn't deal well with it.  Whether anything is drawn varies
with the scale.  Attached C program reproduces this through just cairo.
