/*  Console Variables are grouped under gAdvancedResolution. (e.g. CVAR_PREFIX_ADVANCED_RESOLUTION ".Enabled")

    The following cvars are used in Libultraship and can be edited here:
        - Enabled                                       - Turns Advanced Resolution Mode on.
        - AspectRatioX, AspectRatioY                    - Aspect ratio controls. To toggle off, set either to zero.
        - VerticalPixelCount, VerticalResolutionToggle  - Resolution controls.
        - PixelPerfectMode, IntegerScale.Factor         - Pixel Perfect Mode a.k.a. integer scaling controls.
        - IntegerScale.FitAutomatically                 - Automatic resizing for Pixel Perfect Mode.
        - IntegerScale.NeverExceedBounds                - Prevents manual resizing from exceeding screen bounds.

    The following cvars are also implemented in LUS for niche use cases:
        - IgnoreAspectCorrection                        - Stretch framebuffer to fill screen.
            This is something of a power-user setting for niche setups that most people won't need or care about,
            but may be useful if playing the Switch/Wii U ports on a 4:3 television.
        - IntegerScale.ExceedBoundsBy                   - Offset the max screen bounds, usually by +1.
                                                          This isn't that useful at the moment, so it's unused here.
