wip/gtkmathview 0.8.0 NetBSD

GtkMathView is a C++ rendering engine for MathML documents. It provides an interactive view that can be used for browsing and editing MathML markup. GtkMathView reads MathML documents by means of a frontend whose purpose is to traverse the MathML document (or part of it) and to appropriately instantiate GtkMathView's internal data structures that are suitable for rendering it. GtkMathView renders MathML documents through a backend whose purpose is to provide an abstraction of the platform-specific capabilities (available fonts, drawing drawing primitives, and so on).
