> Other vulkan extensions are gated behind platforms: wayland, xlib, ...
> This one depends on library version and I hope I handled it right,
> did I took the right approach?
>
> Also what if extension requires both platform and libary version?
> Should *_entrypoints_gen be able to support several defines per extension?

We used to have this in anv, but Jason dropped it. It's not clear to me from the
commit message for the review why.
Adding him.

Is this change present in the upstream XML? Generally we don't hand edit the XML
from Khronos, unless the change is upstream already or on its way upstream,
since the next update to the XML would delete this change.
