 The aim of the project is to create an easy-to-use, lightweight, cross-browser, general-purpose 3D library. The current builds only include WebGL and WebGPU renderers but SVG and CSS3D renderers are also available as addons.

Subject: [PATCH 2/2] Add validation for BufferAttribute matrix methods

- Add itemSize validation to applyMatrix4(), applyNormalMatrix(), and transformDirection()
- These methods now warn and return early if itemSize is not 3
- Prevents silent failures and incorrect results when used with wrong itemSize
- Improves consistency with existing documentation that states these methods only work with itemSize 3
