cssvalue: Change color transitions to run premultiplied Previously, the unpremultiplied values from the GdkRGBA were taken. Now we premultiply the color values as specified by the CSS specs. This is only relevant when transitioning with translucent colors. An example is the halfway transition between transparent (0, 0, 0, 0) and white (1, 1, 1, 1). Previously, all 4 values where transitioned separately and the result was semi-transparent gray (0.5, 0.5, 0.5, 0.5). By depending on the alpha value, the result is now semi-transparent white (1, 1, 1, 0.5) which is what one would naively expect.
