Creates map of indices to tc.data representing the curves. For bezier curves it uses the layout [L0, P0, R0, L1, P1, R1, L2, P2, R2], where [P0, P1, P2], [L0, L1, L2] and [R0, R1, R2] are positions, left handles and right handles respectively. Other curve types just use the positions [P0, P1, ..., Pn] of the control points directly.
