Can JavaFX do CAD?

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.
