As flipping can be considered as a way to "rotate" things, it makes sense to have it used as a center for flipping too.i
This is useful for objects that are moving and can be flipped according to if they are going left or right: they can now
be rotated and flipped "properly" (properly means that the center will stay at the same position when flipped/rotated)
This means that the center point won't move when the sprite is rotated or flipped.
The origin is still used as the point not moving in case of scaling. (this make sense because scaling is about the size, and origin about positioning)
This remove some calculations in the renderers, but add others in getDrawableX/Y and getCenterX/Y in case of flipping.
* Rename onOwnerRemovedFromScene to onDestroy (because it can be now called when a scene is destroyed)
* Fix it being not called when a scene is destroyed (so behavior don't get a chance to clean up what they have created)
* Fix onCreated being called before the object is fully initialized (for custom behaviors or behaviors relying on an object type)
* "Bug" is fixed by ignoring edges when doing collision tests for
the platform engine.
* Also add an option to round coordinates and ensure pixel-perfect
alignement of characters on platforms (on by default)
* Also add an optional parameter to ignore edges when
doing a collision test (or when separating objects)
AABB was not properly computed for rotated objects or objects
with a non default center/origin. This could create issues while checking
collisions and for behaviors/logic relying on spatial hashing (platformer,
pathfinding).
* Add benchmark to compare the speed of the implementation for non rotated object
(simple/faster) and for rotated objects (always exact but 12-15% slower).
* Add a method to render AABB of objects to ease debugging.
* Also add a test game.
* Add tests for AABB
* Add tests for getHitboxes for gdjs.SpriteRuntimeObject
Positioning was not made using center of object which was making it inconsistent
with other related actions/expressions (like the expression to get distance).
