Support the CSS z-index property to control drawing order of objects #156

Closed csvurt closed 8 years ago

csvurt commented 8 years ago

We'd like to be able to force some objects to always draw on top of or below others regardless of their spatial relationship in the scene. The CSS z-index property would be a perfect fit for this.

The rendering behavior should follow the same rules as positioned HTML elements do. z-index should also be considered in the picking passes.

Right now this feature breaks if xml3d.css is not included in the page because mesh, group and model elements must have position: relative (or absolute) for the browser to calculate the z-index property correctly. I think we should set the position property during configuration of these elements instead of relying on an external CSS file like this.
