Window X Start Position bits [9:0]
These bits determine the X start position of the window in relation to the top left corner of
the displayed image. Even in a rotated orientation, the top left corner is still relative to the
displayed image.
Window Y Start Position bits [9:0]
These bits determine the Y start position of the window in relation to the top left corner of
the displayed image. Even in a rotated orientation, the top left corner is still relative to the
displayed image.
When pixel doubling or pixel halving is enabled, these registers should be programmed
with the pre-resized coordinates.
