Ruiyu Ni 5ae0723355 MdeModulePkg/FrameBufferBltLib: Fix a bug causing display corrupted ... The Graphics Output Protocol's mode information specifies the PixelsPerScanLine property. Most of the time this is identical to HorizontalResolution. However, due to alignment requirements etc. it may be slightly larger. I.e. each scan line will have some "pixels" that are not visible on the screen but consume space in the frame buffer. If the graphics output protocol correctly initializes HorizontalResolution to 1366 and PixelsPerScanLine to 1376. As a result the graphics output is broken. If setting HorizontalResolution to 1376 instead, the output is fine (except for 10 invisible pixels on the right of the screen). The patch fixes this bug by using PixelsPerScanLine when calculating the line width.
