Oracle Drags Its Feet in the JavaScript Trademark Dispute
Oracle seeks to dismiss fraud claims in the JavaScript trademark dispute, delaying the case and avoiding questions about its right to the name.

Convert gradient to hard-edged gradient with 11 segments and 0 smoothness.
grad := colorgrad.Rainbow().Sharp(11, 0)
This is the effect of different smoothness.
