Added export of multiple UV coordinates and vertex colour attributes.
A debugging option to export the strands without using the cache has also been removed.
The curve segment primitive has been added. This includes an intersection function and changes to the BVH.
A few small errors in the line segment intersection routine are also fixed.
Patch [#33445] - Experimental Cycles Hair Rendering (CPU only)
This patch allows hair data to be exported to cycles and introduces a new line segment primitive to render with.
The UI appears under the particle tab and there is a new hair info node available.
It is only available under the experimental feature set and for cpu rendering.
