Jitter raster occlusion camera to reduce false positives.
Due to the low resolution of the occlusion buffer, small gaps between occluders can be closed and incorrectly occlude instances which should show through the gaps. To ameliorate this problem, this PR jitters the occlusion buffer over time, making it more likely an instance will be seen through a gap. This is used in conjunction with an occlusion timer per instance, to prevent instances flickering on and off rapidly.

Higher values will result in more accurate occlusion culling, at the cost of higher CPU usage. The occlusion culling buffer's pixel count is roughly equal to [code]occlusion_rays_per_thread * number_of_logical_cpu_cores[/code], so it will depend on the system's CPU. Therefore, CPUs with fewer cores will use a lower resolution to attempt keeping performance costs even across devices. See also [member rendering/occlusion_culling/bvh_build_quality].
