Refactor|Cleanup|libgui: Cleaning up Canvas/CanvasWindow and window init/drawing
Cutting down on the cruft. The Qt 5 OpenGL APIs allow for a cleaner implementation of window initialization and refresh. The "frame swapped" signal is particularly helpful.
Using an audience for drawing the window contents is not the best idea because the order of audience callbacks is unspecified. Now the draw() method is a simple virtual method call back to the parent CanvasWindow.
GLInfo now checks for the EXT_timer_query extension.
