Support alpha channel initial work

In this initial work, all (almost) color properties are converted into a new type (float4) to
support an alpha channel. Alpha channel option is shown in the color dialog for Layer and Scene
background properties only. The following is remaining:
- Scene background alpha doesn't work in the editor (works in the viewer RT1)
