[cairo] Path Gradients

[Bobby Salazar]

I don't agree, path gradients are very useful for non-radial gradients. Suppose you wanted to add a shadow behind/below a non-radial path? A path gradient makes this trivial, and without a path gradient it can be near impossible for some shapes.

Also, take a look at the buttons on the calculator in the below screenshot. They would not be possible without (the "simple" type of) path gradients.
