Title: Tick angles point along gridlines regardless of aspect ratio

I had previously computed the tick angle by advancing a fixed distance in axes coordinates. This was wrong, because the axes coordinates always run from 0 to 1, regardless of aspect ratio. The solution in this patch is to compute the offsets by advancing in figure coordinates (i.e., pixels).

Fixes #62.
