LineMaterialParameters: extends ShaderMaterialParameters not MaterialParameters

[puxiao]

class LineMaterial extends ShaderMaterial { ... }

So, the constructor parameters should also extends ShaderMaterialParameters , not MaterialParameters .

export interface ShaderMaterialParameters extends MaterialParameters {
    ...
    linewidth?: number | undefined;
    wireframe?: boolean | undefined;
    ...
}

So, We can remove linewidth and wireframe from LineMaterialParameters.
