The scales, as mentioned, works with pseudo scales but that is sometimes a bit
cumbersome. This is why a special \type {\numericscale} primitive has been
introduced.

+After doing this with text, I wondered if we can avoid multiple sizes of an

+the same font, but scaled. And, indeed, experiments show that this can be done,
+although the math renderer had to be adapted to it. So, for now it's an
+experiment. Users have to check if things are okay. Also, we have slightly
+different rounding than with normal scaling. Of course the big advantage is that
+we have less instances (math can add up more than text as every size has in fact
+three instances).
