Description

This came up in Bug #1678 (closed).

We may optionally replace our own vector math functions and replace them by SVML, or some alternative:

Pro:

• We get immediate support for other functions like asin, erf, ...
• Binary sizes would slightly reduce for people who use SVML anyway.

Maybe Contra: We could get worse performance (someone needs to check)
