=== Description

Vulkan apps may wish to export or import device memory handles to or from
other logical devices, instances or APIs.

This memory sharing can eliminate copies of memory buffers when different
subsystems need to interoperate on them.
Sharing memory buffers may also facilitate a better distribution of
processing workload for more complex memory manipulation pipelines.
