Add a blending mode option to clip properties
Pitivi can already do simple alpha blending between layers, it would be cool it if was also possible to use different modes like in AE/GIMP/Photoshop/etc.
There's a ton of modes but only a few are really used often:
- Normal
- Add
- Substract
- Multiply
- Divide
- Overlay
- Soft Light
- Burn
- Dodge
- Difference
- Exclusion
