Feature request: Accept negative values for col-start-, col-end-, row-start- & row-end-

[wongjn]

Could we perhaps consider supporting negative values for the col-start-, col-end-, row-start- and row-end- utilities? Negative values allow one to offset from the end of the axes, rather than the start.

I believe it would be the case of adding { supportsNegativeValues: true } to the third parameter of these calls – I can open a PR if this proposal would be acceptable.
