bug_57 extreme Extreme version of the bug provoked with ridiculously large ray_step_size = 5.

version 05de344

Change vertical field of view to 10.0 for cropping and use --resolution_factor 2 --samples 10.

bug_57_base Default state: ray_step_size = 0.25.

bug_57_smaller_max_error Reduced ray_max_error = ray_step_size * 1e-4.

bug_57_smaller_step_size Reduced ray_step_size = 0.1 and ray_depth = 500.
