Sets up the shading rate map to use a native 3D API shading rate object src.
true
when successful, false
when not supported.object
field of src is expected to contain an id<MTLRasterizationRateMap>. Note that Qt does not perform anything else apart from passing the MTLRasterizationRateMap on to the MTLRenderPassDescriptor. If any special scaling is required, it is up to the application (or the XR compositor) to perform that. Reimplemented from QRhiShadingRateMap.

overridevirtual |
Releases (or requests deferred releasing of) the underlying native graphics resources.
Safe to call multiple times, subsequent invocations will be a no-op then.
Once destroy() is called, the QRhiResource instance can be reused, by calling create()
again. That will then result in creating new native graphics resources underneath.
The QRhiResource destructor also performs the same task, so calling this function is not necessary before deleting a QRhiResource.
Implements QRhiResource.
