conicFunction in std::sketch

WARNING: This function is experimental and may change or be removed.

Add a conic section to an existing sketch.

Name	Type	Description	Required
`sketch`	`Sketch`	Which sketch should this path be added to?	Yes
`interiorAbsolute`	`Point2d`	Any point between the segment's start and end. Requires `endAbsolute`. Incompatible with `interior` or `end`.	No
`endAbsolute`	`Point2d`	Where should this segment end? Requires `interiorAbsolute`. Incompatible with `interior` or `end`.	No
`interior`	`Point2d`	Any point between the segment's start and end. This point is relative to the start point. Requires `end`. Incompatible with `interiorAbsolute` or `endAbsolute`.	No
`end`	`Point2d`	Where should this segment end? This point is relative to the start point. Requires `interior`. Incompatible with `interiorAbsolute` or `endAbsolute`.	No
`coefficients`	[`number`; 6]	The coefficients [a, b, c, d, e, f] of the generic conic equation ax^2 + by^2 + cxy + dx + ey + f = 0. If provided the start and end tangents will be calculated using this equation. Incompatible with `startTangent` and `endTangent`.	No
`startTangent`	`Point2d`	The tangent of the conic section at the start. If not provided the tangent of the previous path segment is used. Incompatible with `coefficients`.	No
`endTangent`	`Point2d`	The tangent of the conic section at the end. Incompatible with `coefficients`.	No
`tag`	`TagDecl`	Create a new tag which refers to this segment.	No
