How do I skew a shape gradient?
I assume this should be trivially easy, but for the life of me I can't figure out how to do it, and 20 minutes of googling hasn't given me any clues.
I started with a rectangle shape and then applied a gradient to it. Then I skewed the rectangle so that the top edge was shorter than the bottom edge, expecting that the gradient would also be skewed, but it is not:

So how can I get the gradient to skew along with the shape? (*Without* rasterizing the shape, which makes it too hard to work with.)
Thanks for your help!
