[FR] scale to given size

[noerw]

Thanks for the amazing utility!

It would nice to be able to scale an object via a resulting size, not via a scale factor.
Something like ./obj-magic -O --scale-tox 1.0 --scale-toz 1.0 file.obj

(My top level goal is to fit a object into the [1,x,1] interval, so maybe --fitxz 1.0 would be an option as well)
