Show HN: 2D Graphics on Modern GPU

The most promising use case for the work is likely CAD tools, where there might be quite complex scenes and it’s not necessarily practical to organize the UI drawing around GPU primitives (as opposed to 3D games, for example). Similar to the simplistic rendering strategy above, a simple approach to tile generation would be to have a thread per tile (~12k threads), each of which sequentially traverses the scene graph. The basic structure is there, though; the traversal of the scene graph and generation of tiles is at heart sequential, not relying on tricky GPU-compute techniques such as sorting.
