Jean-Yves Avenard 11ac9e9cf8 Bug 1540581 - P6. Tidy some C++ declarations in gfx/. r=gerald,jrmuizel
* Remove redundant virtual keywords
* Mark all destructors of inheriting classes as virtual for clarity
* Mark all classes without virtual destructor as final (exposed errors)
* Make destructor virtual where it needed to be (some were missing)
* Replace empty ({}) code declaration in header with = default
* Remove virtual unused methods

I probably missed some, it quickly became a rabbit hole.
