-/**
-
- Vectorscope.
-
- The basis matrix for converting RGB to YUV is:
-
-mRgb2Yuv = r =
-
- 0.29900 0.58700 0.11400 1.00000
- -0.14741 -0.28939 0.43680 x 0.00000
- 0.61478 -0.51480 -0.09998 0.00000
-
- The resulting YUV value is then drawn on the circle
- using U and V as coordinate values.
-
- The maximum length of such an UV vector is reached
- for the colors Red and Cyan: 0.632.
- To make optimal use of space in the circle, this value
- can be used for scaling.
-
- As we are dealing with RGB values in a range of {0,...,255}
- and the conversion values are made for [0,1], we already
- divide the conversion values by 255 previously, e.g. in
- GNU octave.
