Mirror/Flip a clip

@stefan2140

Drag a plugin from the Video Effects in the Resources window to the timeline and enable the "Show Controls" icon.

Rotate - is the most versatile

Then there are: Flip, F_hflip, and F_vflip

For the horizontal/vertical flip, there is a dedicated native plugin: "Flip".

Thank you, Phyllis and Andrea.
The 'Flip' was what I needed.
I admit... I scrolled through the effects... but was a bit lazy to find to right one.
