The draft spec lives at
http://kiwitree.net/~chadv/vulkan/#1.0-VK_EXT_queue_family_foreign.
I plan to ask Khronos to merge the spec this week.
By itself, this extension does nothing. It's only useful in its
interaction with other external memory extensions.
In the short term, at least, anvil will do nothing on transitions
to/from the foreign queue. There does exist, though, some possibility to
eventually distinguish between transitions on
VK_QUEUE_FAMILY_EXTERNAL_KHR and VK_QUEUE_FAMILY_FOREIGN_EXT for ccs_e
images.
