Alon – big news from GL Common F2F in Bellevue was the contribution of XGL from AMD and the group agreeing to use it as starting point for GL Common
Alon – I raised at the meeting and on the today’s GL Common call how XGL deals with platform integration and interoperation with other Khronos APIs, open issue
Alon – need to decide how to take things forwards, identify any problems such as IP zone issue if that's a problem, how we should structure discussions given GL progression.
...
Alon – If we could make sure that in two weeks time we have that, possibly have some sort of straw poll to see if we have agreement on how to proceed
