Re: [Public WebGL] For review: ANGLE_timer_query extension

Timer query is a bad match for tiled renderers, e.g. PowerVR. As food for thought: even if this becomes available, there will be a huge proportion of low-end/mobile GPUs that will likely never be able to leverage the data from this sort of API.

Render-pass level timing is, as I understand it, more viable on tilers.

That's utter nonesense. You didn't think this trough. A so inclined programmer might capture a call stack of his drawing. Where's your "known order" now? Nowhere. It's gone. It had structure before you mangled it into a flat list. A flat list is not the only usecase of queries. Stop dictating application structure to people wanting to use timer queries. Think trough what people might want to do with them before assuming "A list is what anybody will ever need".
