New Feature: Color Blend Operator

Previously, to modify a color, you'd have to increase or decrease the Hue, Saturation, or Brightness. I never felt this was particular intuitive (even though everybody claim the HSV palette is very intuitive).

I've added a simple Blend operator, which blends the current color with the stated color (weighted by the given strength). See the example screenshot.

The syntax is: blend {color} {strength}

A strength of 1.0 will weight the current and new color evenly. Colors are mixed in HSV color space. Hue's will wrap around. Saturation and Value are clamped to [0,1].

Notice that since the mixing is performed in HSV space, the result may seems counterintuitive. For instance blending a red color into a blue color, may have intermediate green steps (since you are change the hue - so you will move around on the HSV color circle).

In Subversion now, and part of Structure Synth 1.0 when released.
