\note Setting \a mipmapMode to a value other than \c None implies that
images for all relevant mip levels will be provided either via
\l{QRhiResourceUpdateBatch::uploadTexture()}{texture uploads} or by calling
\l{QRhiResourceUpdateBatch::generateMips()}{generateMips()} on the texture
that is used with this sampler. Attempting to use the sampler with a
texture that has no data for all relevant mip levels will lead to rendering
errors, with the exact behavior dependent on the underlying graphics API.
