Input formats
00 (hex) = YUV 4:2:0, semi-planar
03 (hex) = YUV 4:2:0, planar
08 (hex) = YUV 4:2:2, semi-planar
0B (hex) = YUV 4:2:2, planar
0F (hex) = RGB or YUV 4:4:4, planar
24 (hex) = 1-bit indexed
45 (hex) = 2-bit indexed
66 (hex) = 4-bit indexed
87 (hex) = 8-bit indexed
A0 (hex) = packed YUY2 4:2:2
A1 (hex) = packed UYVY 4:2:2
AC (hex) = 16-bit variable contents 4:4:4
E8 (hex) = 32-bit variable contents 4:2:2

PFU_LSIZE
R/W
0
Line size
Denes size of input window
1 = one pixel
Remark: Internal buffer lines are only 1024 pixels. Horizontal
and vertical scaling need to be ordered such that the
intermediate result fits into 1024 pixels buffer lines.
