ctx.query is not working #72

According to this entry in Babylon

GPU timer require a special extension (EXT_DISJOINT_TIMER_QUERY) in order to work. This extension has been disabled due to Spectre and Meltdown on all major browsers. This is still possible to use by enabling the flag gfx.webrender.debug.gpu-time-queries on firefox at the moment. This should be re-enabled soon in the browsers.
