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.

With embedded systems gaining high resolution displays and powerful CPUs, the desire for sophisticated graphical user interfaces can be realized in even the smallest of systems. While the CPU power available for a given power budget has increased dramatically, these tiny systems remain severely memory constrained. This unique environment presents interesting challenges in graphical system design and implementation. Using ideas from modern window systems in larger environments, TWIN offers overlapping translucent windows, anti-aliased graphics and scalable fonts in a total memory budget of 100KB.

litehtml is the lightweight HTML rendering engine with CSS2/CSS3 support. Note that litehtml itself does not draw any text, pictures or other graphics and that litehtml does not depend on any image/draw/font library. You are free to use any library to draw images, fonts and any other graphics. litehtml just parses HTML/CSS and places the HTML elements into the correct positions (renders HTML).

The MATE control center contains configuration applets for the MATE desktop, allowing to set accessibility configuration, desktop fonts, keyboard and mouse properties, sound setup, desktop theme and background, user interface properties, screen resolution, and other MATE parameters.

The SciPlot Widget is a widget capable of plotting Cartesian or polar graphs, including logarithmic axes in Cartesian plots. The widget is subclassed directly from the Core widget class, which means that it does not depend upon any other widget set. It may be freely used with Athena, Motif, or the Open Look/Xview widget sets. (There is optional Motif support that causes the widget to be subclassed from XmPrimitive. See the man page.)

This utility allows users to configure Qt5 settings (theme, font, icons, etc.) under DE/WM without Qt integration.
