[Bf-cycles] point density doesn't appear correctly

[Sergey Sharybin]

Ah, you're right.

But without being able to reproduce the issue can only guess that maybe
it's a sampling issue Did you try returning constant 1.0 for the densities
of the texture?

Another possibility is that you don't have ATTR_STD_GENERATED_TRANSFORM
attribute calculated.

In any case, it's all quite tricky to tell where exactly the issue without
an example which demonstrates the issue.
