Flow up, proportional colour
 

I have a simple but powerful feature request. I'd like the colour of a task bar in the GANTT chart to be proportional to the resources assigned. i.e. if two resources are assigned to one task and one has a blue style and the other red then the task bar would be half red and half blue.

I'd also like the colours to flow up to the group bars. i.e. if 75% of the days of the tasks within a group are assigned to a resource with a red style and 25% to a resource with a blue style then the group bar would be 75% red and 35% blue.

Is this possible?
