[Pharo-users] Athens and radial gradient

Hello, I wanted to use Athens API to define a radial gradient and I saw that the class RadialGradientPaint only had one radius as instance variable and it seemed to me it was passed as the end radius while the start radius was set to 0. Does it mean that if I want to define a start radius different from 0 I need to call the backend directly ? Thanks, Matthieu
