(thank you to michael for the assistance, above).

as we had people say that it was "not obvious" what or why equivalence with 
Khronos OpenCL opcodes is being proposed, we have created a special section 
with an "equivalence" table between the proposed opcodes and the Khronos 
OpenCL opcodes.

this table makes it abundantly clear how obvious the need for these opcodes 
is, how much of a no-brainer decision it is, and why "quantitative 
analysis" - *for these opcodes and these opcodes alone* - is completely 

other opcodes (SLERP, LERP, CORDIC, Vector Normalisation) are *NOT* 
obvious, and *WILL* require further research and careful analysis.
