-----------------------------------------------------------------
PDFJS-5526-p13_reduced2.pdf has a translation, then a transparency group which
has a tiling pattern. Somehow the translation is lost and the pattern isn't
translated. The pattern itself is correct, i.e. TilingPattern.getImage() has
the correct image.
PDFJS-5526-p13_reduced1.pdf is the same but the pattern itself has a
transparency group. Here the pattern image itself is bad too. That part can be
solved the same way as gs-bugzilla692217 (see [a few days
ago|https://issues.apache.org/jira/browse/PDFBOX-3000?focusedCommentId=15783298&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15783298]).
PDFJS-5526-p13_reduced3-nogroup.pdf is the same but no transparency group
dictionary, i.e. ordinary xobject forms. That one renders fine.
