Subject: Change qopenglext to match official Khronos headers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Otherwise we can hit issues when other versions are included, as
ptrdiff_t while having the same length is not the same type as signed
long long on MSVC.
