v0.4.0

• GD-ADF solver
• All traits and shapes are now generic over Float
• New example 06_custom_primitive
• Remove unnecessary DrawSync trait
• Remove obsolete error-chain in favour of anyhow
• Rewrite documentation and tests

v0.3.1

• Shape now provides union, subtraction, intersection, smooth_min.
• Added 18 more shapes.

Known issues

A non-uniform SDF scaling distorts the euclidean space, yielding incorrect distances.
Therefore in next release, Shape::scale(Vector2D<T>) will be changed to Shape::scale(T).

v0.3.0

• The matryoshka trait of Shape::rotate, translate, scale together now form affine homomorphism, removing the need of specifying it in all of the shape types.
• impl <Cutie> Draw<RgbaImage> for Texture<Cutie, Fn(Point2D) -> Rgba<u8>>

v0.2.0

Added generic draw capabilities;
Added documentation;
Added more examples and unit tests.
