Bring back gradiant themes?

[cindy]

During a recent upgrade, I noticed some of the themes were gone. Was there a reason for removing them in 907e68d?

Gradient themes are more difficult to support. And them also have to be implemented in js code here:

fx/npm/index.js

Lines 618 to 633 in 1952074
