Someone with iOS knowledge please address the C++17 issue reported on the 
interest list and provide a conclusion for us here. 

TL;DR:
  items/qquickshadereffect.cpp:511:20: error: aligned allocation function 
of type
       'void *(unsigned long, enum std::align_val_t)' is only available 
on iOS 11 or newer

The problem goes away compiling under C++14. Is it reasonable to require iOS 
11 by the end of 2020?
