Function transform 

pub fn transform(offset: f32, axis: Axis, transform: &AffineTransform) -> f32

Projects a scalar delta along a given axis through a 2D affine transform.

Parameters

• offset: The delta along the X or Y axis.
• axis: Which axis the delta corresponds to.
• transform: The 2×3 affine transform matrix.

Returns

The transformed scalar offset in surface space.
