[DONE] Vectorscope suggestion - I/Q lines

[3pointedit]

A1ex, I notice on the site front page that the vectorscope might be coming soon. Have you considered adding a skin tone line to the scope?
The "I" line in a YIQ color space lays along the axis of human skin color (regardless of race/skin type).

Check out http://en.wikipedia.org/wiki/YIQ I see that there are already color indicators, but all the vectorscopes I have used retain the I axis even if used for PAL YUV space.

Interesting for me, thanks for the link.

Done, can you check if the slope of I/Q lines is correct?
