- Variable loops are controlled using the tenv.maxloop(newmax) function to set the loop counter max. This is a wrapper around setting tenv.maxj.
- Add tenv.relayer(newlayer) function for changing the Layer of an output line.
- Add tenv.restyle(newstyle) function for changing the Style of an output line, despite this usually breaking positioning/sizing information.
- tenv.maxloops is an alias for tenv.maxloop.
- tenv.loopctl(newj, newmaxj) controls both loop variables if anyone wants to do that.
This closes#753 but documentation still needs to be written.
