VaryingIsDead()

static bool SkMeshSpecificationPriv::VaryingIsDead ( const SkMeshSpecification &  spec, int  v  )

inlinestatic

A varying is dead if it is never referenced OR it is only referenced as a passthrough for local coordinates. In the latter case, its index will returned as PassthroughLocalCoordsVaryingIndex. Our analysis is not very sophisticated so this is determined conservatively.
