Comment 7 for bug 713064

Ok , it seems the reverse of what I was saying is true. The old inkscape code did the correct thing, and it seems this may be a core bug in the SVG color matrix filter, because a simple test is showing it's incorrect in Firefox, and Chrome as well.

The RGB Float values of .5, .25, .25 are not even close to the correct color. This should result in the same color as we get with the Byte values 127,63,63 else where. Instead of a reddish wine color I get almost a salmon pink.

Looks like the only solution at this point is to use floods to get the correct color, and desaturate to pull my masks to comp with. Makes this filter unnecessarily complicated.
