renderer.resize does not resize diffuseTexture and normalsTexture

[tststs]

Hi there,

just played a bit with pixi-lights but after calling the resize method of the renderer it looks like this:

before:

after:

I fixed the problem by resizing diffuseTextureand normalsTexture.

resize: function (width, height)
    {
      PIXI.WebGLRenderer.prototype.resize.call(this, width, height);

      if (this.diffuseTexture && this.normalsTexture) {

        this.diffuseTexture.resize(width, height);
        this.normalsTexture.resize(width, height);
      }
    },

I don't know exactly if this solves the problem entirely and it surely could be made better than checking for this.diffuseTexture && this.normalsTexture so there is no pull request.

i did the check because WebGLRenderer.prototype._initContext calls the resize method before this.diffuseTexture and this.normalsTexture are instantiated.

greeting from berlin, tststs
