In https://github.com/KhronosGroup/WebGL/pull/2076 a separate version of EXT_disjoint_timer_query was defined for WebGL 2.0, re-using the main context's query object type, and eliminating the redundant entry point. This extension is queried under getExtension('EXT_disjoint_timer_query_webgl2'). The WebGL 1.0 version isn't exposed in WebGL 2.0.
This needs to be split off in Chrome's implementation.
Kai, may I assign this to you?
