Fix segment fault with material previews

This fix solves the issue with multiple previews at the same time. Maybe there wll be a more general solutions in render preview module, but we need keep the system running.

Fix render triangle size increment error.

Fix fileread error again.

Fix taper on segment_count==1 situation

Fix detail reducing bugs

Chain first level preview ok. Simplification have bugs.

Cycles: Several emitters per leaf in light tree

This commits makes it possible for leaf nodes in the
light tree to have more than one emitter. This reduces
the maximum depth of the light tree which makes the
traversal of the tree faster but the sampling code
is slower if a leaf with several emitters is found.

Technical details:
-- If cost of splitting in build is larger than the
energy of the node then we create a leaf instead
of splitting.
-- Maximum emitters per leaf is now set to 64
-- During traversal if a leaf with several emitters
is found then we sample one of these based on
the importance of each emitter. This is calculated
on the fly and therefore a CDF generation without
dynamic allocation was implemented.
- Moved the distribution id to node id lookup from
light_distribution_pdf() to light_bvh_pdf().
