Pointer events cleanup and alignment

[davidaurelio]

• Cleans up event handling in the svg renderer.
• adds “deltaX/Y” and “diffX/Y” to regular “pointermove” events as well (not only drags) when triggered by mouse events.
• adds “deltaX/Y” to “pointermove” and “drag” events when triggered by touches
• does not send unnecessary drag events to the runner.
• Stops memory leaking from touch events.

Thanks, looks good. What about tests?

I can’t tell by glancing through this, but does it or would it make sense to include the diffX/diffY from the start coordinate for drag events rather than (or in addition to) the last event emission?

That way things like https://github.com/uxebu/bonsai-demos/blob/gh-pages/demos/draggable-shapes/index.html#L49 can be handled by bonsai and userland doesn’t need to keep track of that state?

[davidaurelio]

Yes, absolutely. I’m already working on it in the next branch.

• diffX/Y will be offsets from the start of the drag
• deltaX/Y will be offsets relative to the last event (also fired for mousemove)

Awesome. 👍
