Added postprocessing example.

For this had to extend WebGLRenderer a bit:

- MeshShaderMaterial now can take non-specific float array uniforms as "fv1"
  (there is already "fv" type for array of 3-item-vectors, which probably should be renamed to "fv3" to be consistent)

- render method has yet another parameter "clear" for clearing newly set framebuffer (defaults to true).
  This is a bit hackish but it seems necessary to control this somehow. I didn't manage to replicate
  desired behavior just with autoClear.

- another dirty thing is accessing GL context from the application side:
    renderer.context.disable( renderer.context.DEPTH_TEST );

    This should be refactored somehow, wrapped in some API call.
