Hi again, the issue of PixelDereferenceAdaptors vs. DataAccessors has been intensively discussed during this review, especially the issues arising when the PixelDereferenceAdaptor must support both rvalue and lvalue use. To get objective data on this, I want to do some experiments comparing the concepts. But to my big surprise, I couldn't find any PixelDereferenceAdaptor in the public part of GIL which supports lvalue use. I'd appreciate if the GIL authors could provide an implementation of a mutable interleaved_rgb_image_view(a_planar_rgb_image) or point me to the right construct.
