"Allow caustics": wrong brightness on caustics at Photon

[nuno1980]

Hello.

At Photon Tracing kernel:

- "allow caustics" unchecked on glossy (or specular) material - brightness is correct on caustics

- "allow caustics" checked - this increases badly brightness on caustics (variable caustics* only is appearing by path tracing method at less than ~0.3 of roughness on glossy ground) - this is BUG.

--> Please should fix the "allow caustics" bugged for avoid the brightness increased for caustics.

* - Learn the "variable caustics" (new)

It does appear to simply be the expected increased incoming light from the Photon Tracing caustics convergence.

Ok. But see below:

At path tracing kernel only (not photon tracing) - 6 laps of 1MS/px of regions picked = 6MS/px

This is CORRECT brightness.
