Re: [edk2-devel] [PATCH - resend] MdeModulePkg/BootLogoLib: Center logo 38.2% from top of screen

["Ni, Ray" <ray.ni@intel.com>]

I have considered the needs of EdkiiPlatformLogoDisplayAttributeMicrosoftRecommended when designing
the BootLogoLib.
The answer was no.
And reason is we can always return a different OffsetY to make sure the logo is in vertical 38.2% position.

      //
      // Center of LOGO is in the vertical position 38.2% when PcdBootLogoOnlyEnable is TRUE
      // Y = (VerticalResolution - LogoHeight) / 2
      // Y' = VerticalResolution * 0.382 - LogoHeight * 0.5
      // OffsetY + Y = Y'
      // OffsetY = Y' - Y = -0.118 * VerticalResolution
      //
      *Attribute = EdkiiPlatformLogoDisplayAttributeCenter;
      *OffsetX   = 0;
      *OffsetY   = -118 * (INTN) GraphicsOutput->Mode->Info->VerticalResolution / 1000;
