* Curve nodes are now clamped to the graph edge when moving a node.
* Fixed stability issues when loading a library in a separate thread.
* Changed the way stretch works in 2d similar to the way it does in 3d. Essentially it now doesn’t matter what the angle of the sprite is, the stretch will be applied indepentantly.
* Changed how weight attribute works. Rather then store weight acceleration as a variable frame by frame where if the weight overtime graph was set to 1 it would just keep adding how heavy a particle is each frame, it now takes the value on the graph and apply the weight linearly.
