  Message : Implement glImportMemoryZirconHandle & glImportSemaphoreZirconHandle Implement import of fuchsia external objects passed by zircon handle. This works exactly the same as with file descriptors. Bug: angleproject:3492 Change-Id: I4d46917dfc5902f00c94550158a9f8073097f0a4 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/1642334 Commit-Queue: Michael Spang <spang@chromium.org> Reviewed-by: Jamie Madill <jmadill@chromium.org>
