Are you asking if you would be permitted to implement this for Cairo?
I'm not sure whether we'd take a patchset that added this, but I'd
certainly be open to a more detailed technical proposal of how you'd
code it.

That looks like a large amount of code for a fairly specific
functionality, what is your thinking as to why it would need to be in
Cairo?

I've wondered about Vulkan myself.  Do you use the OpenGL backend
currently?  What is your interest in Vulkan, that wouldn't already be
met by the current GPU support?  I posted a patchset to upgrade our
OpenGL ES to version 3.0 a few weeks back, which may provide some of
those benefits.  Did you have a chance to look at or test it?

As to OpenCl, what would your thoughts be on how Cairo would make use of
it?
