The render loop has been redesigned.
The OpenGL commands are queued instead of executed immediately.
updatePaintNode() now transfers the commands to the renderer,
which implements all OpenGL related things that used to be in
the Canvas class. The actual rendering is done in response to
beforeRendering signal in the render thread.

[ChangeLog][Renderer] OpenGL rendering moved to render thread.
