Intel GPUs exhibit a number of rendering artifacts. The most substantial being incorrect resolve of reflections. Splitting the reflections_resolve shader into two passes, one for SSR and one for light probes ensures correct rendering and optimal performance on this GPU.

Also resolves an artifact with ambient occlusion wherein the pow(a, b) function causes excessive precision loss. Using an alternative method for power calculation on these platforms resolves the issues.

Just to make sure, is this supposed to be for 3.5 or main?
