Fix floating-point precision issue in accumulation_buffer
...
Fixed an issue that prevented the image from converging.
(Technically, the convergence was happening and the issue was the final
calculation of the displayed colours, but the visual effect was the same as
failure to converge.)

Remove sun from test lighting environment
...
Because multiple importance sampling is not implemented yet,
convergence is quite slow and the single bright light source
of the sun causes the image to be extremely noisy.
