Add extra render call to RenderNonFinite test
Add extra render call to RenderNonFinite test

It appears that due to an issue with the graphics driver on certain
Mac's this test requires the rendering to be done twice. In the past
this was being done ( a bug ... ) but the pipeline changes removed
this and thus this test started to fail.
