[gs-commits] mupdf 1.16.1.epub-prerelease-18 Close down filter process

commit a4bcc86279d6a6b90d8e13a82a3678b1272c57ce

    Close down filter processor in "close" callback, not "END" callback.
    
    The END callback is called when hitting the end of a content stream.
    This is not the same as closing down at the end cleanly.
    Currently there's no difference, but should we for example inline
    XObject forms, we will call END for each inlined content stream.
