cups-filters-1.21.4

[Bruce Dubbs]

New point version.

Putting in hold for too many releases.

Was .3, now .4 : but all recent versions need to be fixed to build with current poppler - so let's go with 1.21.4 while we are doing that.

Now version 1.21.3

[Wayne Blaszczyk]

As a side note, any reason why mupdf is a required dependency and not at best a recommend dependency given that there is a switch (--disable-mutool) to disable it? I'm curious what extra functionality does mutool give on top of qpdf?

[Douglas R. Reno]

My guess is that it has something to do with the functionality of mutool:

renodr [ /sources ]$ mutool --help                                              |
usage: mutool <command> [options]
        clean   -- rewrite pdf file
        convert -- convert document
        create  -- create pdf document
        draw    -- convert document
        trace   -- trace device calls
        extract -- extract font and image resources
        info    -- show information about pdf resources
        merge   -- merge pages from multiple pdf sources into a new pdf
        pages   -- show information about pdf pages
        portfolio       -- manipulate PDF portfolios
        poster  -- split large page into many tiles
        sign    -- manipulate PDF digital signatures
        run     -- run javascript
        show    -- show internal pdf objects

For cups-filters, I'm guessing that it's using the portfolio option. This is just a hunch though, I'm not 100% certain what it does and don't currently have the impulse to check out the cups-filters source code to figure it out.
