Subject: [PATCH] rhi: Add a way to query the parent QRhi from a resource
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Quick3D introduces the need to verify the QRhi when only a
QRhiTexture (pulled out from a QSGTexture) is available. To
enable this, there needs to be a way to retrieve the QRhi
from the QRhiTexture.
