Mat4:perspective
EditSets this matrix to represent a perspective projection.
This can be used with Pass:setProjection, or it can be sent to a Shader for use in GLSL.

| aspect | number | The horizontal aspect ratio of the projection (width / height). | |
| near | number | The near plane. | |
| far | number | 0 | The far plane. Zero is a special value that will set an infinite far plane with a reversed Z range, which improves depth buffer precision and is the default. |
