Hi Benoit

The current draft spec. is insufficient in regards to synchronization
capabilities. I am working on an update which will draw on OpenML and
the recent EGL_ANDROID_presentation_time extension and accounts for the
web approach of having a presentation time for each frame instead of a
pre-set frame rate. The spec. should not be promoted until this update.

It will be easier for accurate synchronization if we had an explicit
present call for the drawing buffer. I know this has come up in other
threads. My current plan is to present 2 alternatives in the updated
spec: with and without an explicit present call. However this is subject
to change according to issues that may come up as I write the draft.

I am delighted to hear a strong request for this extension. It will give
me impetus to get back to it and complete the update.
