All,

Our new proposal for WEBGL_get_buffer_sub_data_async is finally ready. Please take a look and send along your comments and suggestions. Feel free to request comment access if you want to comment on the doc itself.

Note this is a design doc and not a spec, so it will hopefully be easier to read but may not be explicit about every edge case yet.

This doc should mention the core reason for this extension: the inability of some WebGL implementations to support glMapBufferRange. And describe how that led to gl.getBufferSubData() and then this proposal. As far as I can see all the use cases listed would be solved if glMapBufferRange was supported.

Regards
