Because my document is zoomable, I used the same approach SVG->FXML to represent some icons that are used on items throughout the document. This works but I have always felt that it is too heavy for my use-case. Specially since I have the same icon appearing in multiple places, which means I need to reproduce the same node structure in each place instead of using a simple and fast image. I have it on my list to investigate a mechanism to replace these with something that renders the appropriately scaled shapes once to an image that can be re-used by ImageView nodes instead of the duplicating the entire node hierarchy for the shape.
I should put some debug code in my app to count the nodes in the scene graph to get an idea of when the system gets too bogged down.
