Cycles: fix bugs in point and spot light multiple importance sampling * Spot lights are now handled as disks aligned with the direction of the spotlight instead of view aligned disks. * Point light is now handled separately from the spot light, to fix a case where multiple lights are intersected in a row. Before the origin of the ray was the previously intersected light and not the origin of the initial ray traced from the last surface/volume interaction. This makes both strategies in multiple importance sampling converge to the same result. It changes the render results in some scenes, for example the junkshop scene where there are large point lights overlapping scene geometry and each other.
