Constraint Type-Info (shorthand in code = cti): This struct provides function pointers for runtime, so that functions can be written more generally (with fewer/no special exceptions for various constraints).
Callers of these functions must check that they actually point to something useful, as some constraints don't define some of these.
WARNING: it is not too advisable to reorder order of members of this struct, as you'll have to edit quite a few NUM_CONSTRAINT_TYPES of these structs.

This function is a relic from the prior implementations of the constraints system, when all constraints either had one or no targets. It used to be called during the main constraint solving loop, but is now only used for the remaining cases for a few constraints.
None of the actual calculations of the matrices should be done here! Also, this function is not to be used by any new constraints, particularly any that have multiple targets.
