* WiP property animations system
* Use better lerp for Angle property animations.
* Fix handling of offset in sprite component.
* Allow animating some sprite layer properties.
* Allow animating some Transform properties.
Obviously not advisable for server entities, but great for client side entities!
* Improve animation property interpolation handling.
Added a "previous" mode.
Made values that cannot be sanely interpolated fall back to this mode.
* Improve some animation docs.
* Attempted Clyde cleanup, didn't get far.
* Add negation operator to Vector2i.
* Add RenderOrder to ISpriteComponent.
* Post process shaders.
Adds "post process" shaders to sprite component.
These are executed on the WHOLE sprite component (every layer)
in one draw.
This is necessary to implement functional outlines.
