Hi Devs, I have created a PR for this new feature - Svg marker size: change aspect ratio. https://github.com/qgis/QGIS/pull/4912 This feature has been funded by Ville d'Avignon. I probably have to update tests. Please let me now if our implementation si good. Thansk for review. Regards, René-Luc D'Hont 3Liz
