Fixed a crash in the Sweep 2.0 SOP when Cross Section Order is All Cross Sections At Each Curve Vertex and Compute UVs is enabled.

Fixed bugs in a unicode search utility function.

Added prompt for camera state. Fixed computation of focus plane size.

Data parameters with the sidefx::save_value of 0 will save empty strings rather than short vectors. This avoids channels being destroyed on load.

Data parms can now be chain-referenced more than one level using ch() references.

The Alembic SOP now gracefully handles Alembic archives containing degenerate curves.

Added the Copy to Points 2.0 SOP as an HDK example, "HDK Copy to Points", giving an example of complicated caching based on data IDs, multiparm parameters, construction of packed geometry primitives from input geometry, and copying of any primitive types.

When automatically generating a USD Surface Preview material from render-specific VOP node, and when a USD UV Texture primitive is involved, the 'a' output of the texture primitive is wired to the 'opacity' input of the surface primitive.

The Instancer LOP will now create primvars from SOP point attributes if a USD attribute matching the SOP attribute name doesn't already exist. Also made it harder to author invalid (non-array-typed_ primvars with Edit Properties nodes and HDAs.
