- Oh, they are used. But what happens when you need more colors ? The first
- colors are allocated from free pens (and are precise). The next colors
- share an already allocated pen and are probably quite wrong. The major problem
- is that there is no smart decision to what pens are going to be precise
- and what pens are going to be approximated.
