This is one posibility for regular axes. The point is that the texter
can add attributes to be used to typeset the labels. This is
important, since the texter for example might use mathematics (they
even always force the mathmode by default). And somehow this mathmode
attribute needs to be set.

Still other attributes can be set in the graph painter. Its labelattrs
for regular axes painters.

For bar axes there are no texters. Right. But there is still an
similar feature like labelattrs, namely nameatts. (To differentiate
between discrete and continous axes I've used labels vs. names in
regular vs. discrete axes.)
