Swizzling is rendered nearly useless if it requires elaborate syntax or
long names. Currently, if you want the Z and X swapped, you'd use (v,ZYX).

I've considered using lower case but that doesn't work well in the case of
(v,x) since it's quite likely that it'll clash with a local x.

Clashes with macros are possible, but FWIW I've been using this library for
years now and never had a clash (all these names are defined in a separate
header, you don't have to include it if you don't need swizzling.)
