Short description of error
The established node setup for Cycles matcap materials no longer works in 2.76. I don't mind changing the setup if that is what is required, but if there is no way to create matcap materials in Cycles that is a problem. Is this the result of a change of standards for how vector data is handled, or did something just simply break?
This may or may not be related to a bug I submitted on Oct 7th which involved this node setup breaking specifically when Open Shading Language was enabled. (That bug was resolved.)
Exact steps for others to reproduce the error
Observe the .blend when opened in 2.76 rc3 versus in 2.76 - the node setup does not produce a matcap result anymore in 2.76.
