I guess the only one who knows if there will be other resolutions reported for
BAMBOO_PT is you. :-) I wanted to not break any eventual resolution improvements
in the BAMBOO_PT family, but if you say there aren't any, using the BAMBOO_PT
check will be better, as you say.

If you mean something like "features->x_max <<= 5", absolutely. Again, this all
depends on what resolutions are to be anticipated, and which ones should be
scaled this way.
