Hi Siddharth,

Fair warning: The experimental, shifting nature of the API and it's
current pending state landing in Chrome's ToT make this a difficult
effort to contribute to at the moment. There's no guarantee that any
work done at this stage will eventually make it into Chrome (although
obviously I hope it does.)

With that said, there are a couple of areas where some additional
input would be helpful. One of the biggest issues with the current
builds is that extended desktop mode (on all platforms) does not run
at the correct framerate for devices like the Oculus Rift DK2, which
runs at 75Hz. In order to handle that correctly we would need to
invoke "exclusive fullscreen" mode on the browser window after going
fullscreen on the HMD. Any research into how/if that can be done in
Chrome with WebVR would be valuable.

Another potential area of contribution is finding a way to use
SDK-native distortion rendering (like the Oculus SDKs
ovrHmd_ConfigureRendering and related functions) instead of the
re-implemented variants called by GLRenderer today. The current method
works okay, but the ability to use the SDK versions will lessen the
load of maintaining WebVR in the future and ensure that we are always
using the best distortion method available.

These are not small tasks, and will require a good working knowledge
of Chrome's architecture. If you're up for the challenge, though, I
would be glad for the help!
