[Bf-committers] Bf-committers Digest, Vol 45, Issue 5

[Tyler Fric]

Great Suggestions Yves. Now that you mention it I remember running into
the second issue you mention myself. Certain vector math functions would
of course cause problems when converting back and fourth between float
and RGB  and clamping the range but these problems are minor compared to
the flexibility it would give a motivated user. I will update my
proposal accordingly.

Thanks

TF
