libcupsfilters 2.0rc2

[tillkamppeter]

Bug fixes following first bug reports from Ubuntu 23.04 and Fedora 38 users, first distros with libcupsfilters 2.0rc1:

• Ignore unsupported resolution values when preparing a Raster header via cfRasterPrepareHeader() function, to avoid rasterization with wrong resolution (Issue HP Envy 4520 Printing issues from Chrome/Chromium #29), Ubuntu bug: #2022929, Chromium issue #1448735).
• cfRasterPrepareHeader(): When taking default resolution from urf-supported printer IPP attribute, use first value (lowest) of the list, to match the ppdLoadAttributes() function of libppd.
• cfIPPAttrResolutionForPrinter(): List of resolutions is not IPP_TAG_RANGE, corrected the search to use IPP_TAG_ZERO.
• cfIEEE1284NormalizeMakeModel(): Do not consider "XPrinter" as made by Xerox, only "XPrint" is (OpenPrinting CUPS pull request #506).
• INSTALL: Recommend QPDF 11.4.0 as it fixes loss of content filled into interactive forms as (Issue pdftopdf loses entered form data when flattening the PDF #28).
• INSTALL: Fixed some typos.
