set VEX function

These two functions provide a very efficient way of creating a vector/vector4.

Contexts: image3d, chop, cop, pop, sop, surface, displace, fog, light, shadow, photon, cvex

  1. vector set(float , float , float )

  2. vector4 set(float , float , float , float )

These two functions provide a very efficient way of creating a vector/vector4. Each component is assigned from the argument passed in.
