Intro: libgxps is a GObject based library for handling and rendering XPS
documents.

OpenXPS or XPS stands for XML Paper Specification. It is based on XML
and it's a new electronic paper format originally developed by Microsoft
and it serves as a PDF alternative. XPS files are usually created using
"Microsoft XPS Document Writer" in Windows environments. It is now
standardized as an open standard document format.

Quoting Wikipedia: An XPS file is in fact a Unicoded ZIP archive using
the Open Packaging Conventions, containing the files which make up the
document. These include an XML markup file for each page, text, embedded
fonts, raster images, 2D vector graphics, as well as the digital rights
management information. The contents of an XPS file can be examined
simply by opening it in an application which supports ZIP files.

The OpenXPS document format specification supports features such as
color gradients, transparencies, CMYK color spaces, printer calibration,
multiple-ink systems and print schemas.
