Jeroen Bakker 481bc7a777 EEVEE: Update Render tests script
Last month we have been in the process of fixing the render tests of EEVEE-Next.
These render tests had some issues. Currently we are in a state that render
differences can be explained or related to an existing issue.

Having these render tests will also enable testing differences between Metal and OpenGL.

The new setup alters the position of the reflection probe so it doesn't intersect the ground
or the sphere at the same time. An offset was added, which adds a small difference
between cycles and eevee-next renders.

There is a known issue with the HiZ buffers when render size is too small. We change the
reflection probe render size as a temporary fix.
