Latest version of Lunacy (5.9), exporting SVG with linear gradients doesn’t show well in a couple of parsers. It’s because LinearGradient is using non-percentage units for x1/y1/x2/y2 and offsets, instead it uses 0.0 … 1.0 range.
The spec also says default values in %: https://developer.mozilla.org/en-US/docs/Web/SVG/Element/linearGradient#Attributes
Please use % for this. Thanks!
