Hi Daniel,

I was wandering how (if?) are you going to implement the new buffer release
mechanism in Weston GL renderer.

Where do you get the dma_fence object from? If I understand correctly, the
dma_fence has to be signalled by the GL driver after the last glDraw involving
wl_buffer has finished executing on the GPU. 

I checked quickly GL and EGL extensions but I can't see anything that would
export dma_fence object the compositor could return with the wl_buffer.
