the EPS definition language is an almost complete programming language. I am not sure if it is turing complete, but it can display output and do math at least.
I was not expecting this.
This will make getting vector paths from the EPS files either much easier than I expected or ridiculously difficult. We shall see.
And in todays bit of internet weirdness, postscript is not only a turing complete language, it can be used to do stuff like control electronics. This may have to go into my list of future things to play with.
