Shape class sealed

A base class representing various shapes for rendering particles.

This sealed class defines different shapes that can be used for rendering particles. It provides a method to compute the transformation parameters required for rendering particles using the specified shape.

Each shape must override the computeTransformation method to calculate the necessary transformation based on the particle's properties and the shape's specifications.
