Yann E. MORIN 20cbf17e0a support/graph-size: reorder colours assigned to sizes
Now that we can order packages from biggest to smallest, it makes sense
to assign the most aggressive colours to the biggest packages.

As such, reorder the current colours so that we have, in order:
  - red-ish
  - orange-ish
  - yellow-ish
  - purple-ish
  - eggplant-ish (is that even a colour? :-] )
  - some-indeterminate-blue-ish
  - dark-green-ish
  - light-green-ish

For the previous, smallest-first ordering, it does not matter much what
the ordering is: the actual colours are still somewhat-unpredictably
assigned to packages, depending on the cut-off limit...
