Inverted crossfade transition
Steps to reproduce:
- Create a new project
- Create a title clip, write in it "asdf" (C1)
- Import tears_of_steel, drag it in the middle of the title clip to create a clip (C2)
- Drag the C1 to the right until C2 is not 100% covered and a transition is created
- Seek at the beginning and end of the transition, notice C1 opacity goes from 100%->0% instead of 0%->100%.
