v0.4.0

Blurred outlines.

Added

• Added Gauss blurring to outlines.
• Added outline mode parameter (possible values are Solid and Blurred).
• Added outline intensity parameter (for blurred outlines only).
• Added IOutlineSettings interface to make outline settings the same for OutlineBehaviour and OutlineLayer.
• Added OutlineMaterialSet helper.

Changed

• Changed solid outline to use Gauss sampling (to achieve smoother outlines).
• Changed outline implementation to use different passed for horizontal and vertical sampling (to make algorithm complexity linear instead of quadric).

Fixed

• Fixed an issue with OutlineBehaviour not rendering outlines if attached to a GameObject with no renderers.

Removed

• Removed OutlineResourceCache class.
