Hi Cristóvão,

The tick width is currently hard-coded to 0.5pt. While it's not difficult
to add a command to change this parameter, I'm a little wary of making the
line width of ticks easy to change.

Would you be happy making a global change, or do you want to be able to
modify the tick width?

If a global change is enough, it's probably best to modify lines 530 and
533 of the file format.cc,

  obuf << __epix_rule(0.5, 2*sz.tick_size());
  obuf << __epix_rule(2*sz.tick_size(), 0.5);

changing "0.5" to the desired line width in pt. Then build and install the
library as usual. Of course, you'll have to make this modification with
each new release, but I expect the number of Version 1.2 releases to be
very small. :)

Best,
Andy
