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.

The shininess of the planets in the example were left to the default 30.0 which is

(earth) are tweaked to be a bit more shiny and the planets without a specual texture
(the rest) are tweaked to be not shiny at all.

The first FBO we create gets corrupted by something outside
Canvas3D in some cases. E.g. changing the text in an completely unrelated
Text element may corrupt Canvas3D FBOs. This only happens with some GPU
drivers, likely due to a bug in the drivers themselves. To work around
the issue, the first FBO we create is a dummy that we delete once the
real FBOs are done.
