[GEM-dev] [pd-gem:bugs] #228 part_color ignores alpha component

["IOhannes m zmölnig"]

Well yes.
the question is, whether this is actually useful behaviour...
e.g. using a linear domain between (1,0,0,0) and (1,1,0,1) will "interpolate" between red and yellow, but the alpha value will be fixed to 0.

Using Gem 0.93.3 on Windows 7 32bit.

I noticed that when using a part_color, the 4th value (alpha component) is ignored. I looked at the code, and I think it is line 56 of part_color.cpp. When rendering, the color is not passed into the function.
