Fix up the scenegraph/textureinthread example

Force OpenGL, remove the ShaderEffect (it serves no purpose in this
example) and remove deprecated API usage.

Finally, rename the example to opengltextureinthread.

Note that the example's performance is sub-par, but the same is true
with direct OpenGL.
