The patch fixes the problem for me, too; thanks.  However, the delay of
0.1 seconds results in the unconverted file being noticeable before the
image is displayed.  I tried it with a 0.01 second delay and this makes
the image appear practically instantly to me, i.e., I didn't see the
unconverted source, and the paging still worked.  I don't know if this
short a delay is always guaranteed to succeed.
