Slide Directions should be inverted for enter animation

[Robert-K]

If I a GUITransition and set it's Animation Enter property to Slide Right, I'd expect it to slide right on enter (so starting from the left side). Instead it slides left (from the right side) which seems counterintuitive to me.

Hello! When I first programmed it my intention was something like 'slide FROM the right side of the screen', but I think it ended up sounding like 'slide TO the right side of the screen'. Thinking about the screen direction instead of the animation itself may be the reason. It could be changed, but it would be a breaking change, and that's not something I intend to do right now. It can go to a TODO list though, like using more clear names such as 'Slide From Right', 'Slide To Left' and such.
