> On a slightly deeper look at the comparison results between 1.14 and trunk, it looks
like we're missing quite a few embedded images from .doc files.  I initially thought these
could be explained by different handling of macros, but that's not the issue.
> I haven't traced the commit that did it (very likely my fault), but...
> when we call this with a null character run.
> {noformat}
>         // Handle any pictures that we haven't output yet
>         for (Picture p = pictures.nextUnclaimed(); p != null; ) {
>             handlePictureCharacterRun(
>                     null, p, pictures, xhtml
>             );
>             p = pictures.nextUnclaimed();
>         }
> {noformat}
> the null character run then triggers skipping of the picture in this check because {{isRendered(cr)}}
returns false if {{cr}} is {{null}}
> {noformat}
>         if (!isRendered(cr) || picture == null) {
>             // Oh dear, we've run out...
>             // Probably caused by multiple \u0008 images referencing
>             //  the same real image
>             return;
>         }
> {noformat}
