Instead of duplicating the same code in both, `QtGraphics::GetResolution` and `QtSvpGraphics::GetResolution`, create a static helper method `QtGraphicsBase::ImplGetResolution` in their base class and call that. While at it, also move `QtGraphics::GetResolution` to the source file where all of the other `QtGraphics` methods are implemented.
