[GEM-dev] Why is [hsv2rgb] implemented as an abstraction?

[Wesley Smith]

Lua is not really good for doing matrix processing within the script
in realtime as it will incur all kinds of overhead.  It's best instead
to deal with a matrix userdata type with arithmetic metamethod calls
defined.  This will be really fast and completely dynamic.
