Invert X position when mirroring.

[AkaneAngele]

Mirroring lets the artist "resets" how they sees their art. It's like, how other people sees your art the first time.
In game-development, sprites also are re-used to get certain effects without too much problems as walking.
For give an example, TheSpriteResource lets you mirror an image.
Pixelorama too, works very well. But Pixelorama doesn't "update your position".
So, I was wondering about: If mirror mode is changed, horizontal position is also changed.

Otherwise, if you're doing sprites and wanna see how they seems to be mirrored, you need to re-position yourself. You can also move your sprite to the middle (as I do).
