If one puts emphasis on the "isolated" one can see it this way. Stuff is
quite a bit mixed. But then, a file can be loaded without a GUI. All
exporters called from the command line by the -x parameter do this.

There's the 'batch' GUI, a build time option. As far as I can see it
does pretty much the same as 'nogui', which operates when being compiled
for a real GUI but doing a command line export. I think joining these
two could remove duplicate code, which is always good. Then one could
run a binary compiled for a real GUI without actually loading it, run a
few actions and quit without ever seeing a window. No need to have two
separate binaries for such tasks.

The -x option is parsed right in main() in src/main.c, if you want to
start investigating.
