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

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

[Patrick Rudolph]

From: Tim Crawford <tcrawford@system76.com>

Use Microsoft's recommended positioning [1] for the boot logo.

> We recommend that the logo is placed with its center at 38.2% from the
> screen's top edge. This positioning is based on the golden ratio's
> visual aesthetics and matches the Windows 10 design proportions.

Based on Tim Crawford <tcrawford@system76.com> initial commit.

  I am OK for this extension to meet with Microsoft recommendation. This
change is a new feature. Can you submit one BZ

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

[Ni, Ray]

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;
