    //[History]
    // When planar surfaces are tiled, there are HW alignment
    // restrictions about where the U and V planes can be located.
    // Prior to SURFACE_STATE.X/YOffset support, planes needed to start
    // on tile boundaries; with X/YOffset support, the alignment
    // restrictions were reduced (but not eliminated).
    //
    // Horizontal alignment is only an issue for IMC2/4 surfaces, since
    // the planes of all other formats are always on the left-edge.
    //
    // For IMC1/3 surfaces, we must ensure that both the U/V planes are
    // properly aligned--That is, both the YHeight and VHeight must be
    // properly aligned. For all other surfaces (since the U/V data
    // starts at a common vertical location) only YHeight must be
    // properly aligned.

    // [Current] :
    // For Tiled surfaces, even though h/w supports U and V plane alignment
    // at lower granularities GMM will align all the planes at Tiled boundary
    // to unify the implementation across all platforms and GMM will add
    // handling for removing the extra padding when UMDs request for ResCpuBlt
    // operations.
    // For Linear surfaces, GMM will continue to support minimal aligment restrictions
