R_VECADD is a REALTIME operator that adds values to 2-D or 3-D vector VEC1.

VEC2 can be another vector (same dimension as VEC1), or it can be a scalar value. If it is a scalar (single value) then it will be added to every element of VEC1.

NEWVEC is the output vector; it must be the same dimension as VEC1.
If NEWVEC is not specified, the new values will be stored in VEC1.

FLAG: 0 - default
      2 - 2-D vectors (default)
      3 - 3-D vectors
      4 - subtract VEC2 from VEC1 (instead of adding)
      8 - just use 1 value from VEC2 (scalar addition)
