PS_WIN_SZ (Pipe Scaler Window Size)
The scaler outputs the scaled contents to the scaler window, a rectangular
region specified by `PipeScalerWindowPosition` and `PipeScalerWindowSize`
on the output surface.
This register specifies the size of the scaler window. "x" and "y" are
relative to the display device, thus rotation / flipping of planes and pipe
doesn't affect the order of x and y.
This register and `PipeScalerWindowPosition` must be set so that the whole
scaler window is within the output surface; see documentation of
`PipeScalerWindowPosition` for the details of the constraints.
This register is double buffered. Writing to this register will trigger
double buffering arms to this register and all the other Pipe Scaler control
registers so that they are updated at the start of the next vertical blank.
So this register must be written at the end of all the pipe scaler
configuration procedures.
This register's reserved fields are all MBZ (must be zero). So, this register
can be safely written without reading it first.
