The previous iteration was fairly OpenGL-heavy. It's now been separated into
a base class that is OpenGL independent and a derived class that is
OpenGL-based. Over time this should allow for portability away from OpenGL
if necessary.
Previous iteration used probably an excessive amount of threads to make
everything work. New iteration intends to use precisely the amount of logical
threads available and using a moved QObject rather than a subclassed QThread
