VSE video rotation using transform effect is backwards.

Exact steps for others to reproduce the error

  1. Add a transform effect to a video clip
  2. Rotate that video clip using the rotation property

Rotation in the 3d view behaves as expected (clockwise). Here we are rotating a cube 15 degrees:

Rotating a video clip by 15 degrees will rotate counter clockwise

An issue with fixing this is it will break animated rotation. Maybe worth keeping this as a breaking change for 2.8x.

Unfortunately I'll only be able to look at this in April again, so let others take over....

Note the compositor nodes rotation also works this way.

I took another look at this and realized I was confused. I noticed that in the 3d view, if I enter in a positive value for rotation, Blender will convert this value to a negative number (see the GIF). While I still think this is strange, there is no inconsistency with the video sequencer.

3D view isn't related since you will get different results depending on the view direction.
