kind of a hack to make sort ascending work
make default sorting order be descending

2. sorting descending doesn't work otherwise
bugfix for pure backend computation

- do not use locally cached values
parsefloat on $lower and $upper calc

even if there is only one value in an aesthetic, the domain calculation
should still be able to calculate a meaningful min/max
Dates may use color and size scales.
