Re: [Public WebGL] option for suggesting "low power" mode at context creation

In the end such a flag is a hint. It can be ignored. It will be ignored if the usage is already otherwise determined (by other applications running). It's meaning would be fuzzy. It might not be implementable on some operating systems/platforms, and the mechanisms of support will differ from platform to platform. But the basic hint of either "use least power" or "use best performance" is a significant piece of information that neither the GPU, nor driver, nor the OS nor the browser can deduce. I think it would be a good idea to add such a usage flag so that systems which can support different settings, may use that hint if they want to.
