Description

Minor linter fixes.

@zalo The example logs in the browser console this warning:

[.WebGL-0x7f9887061a00]GL ERROR :GL_INVALID_OPERATION : glDrawElements: Source and destination textures of the draw are the same.

Do you mind having a look?

Apologies for the delay; it looks like this is caused by the portal rendering itself to its own render texture.

The fix is simple at line 198:

renderer.render( scene, portalCamera );

should be something similar to:

thisPortalMesh.visible = false; // hide this portal from its own rendering
renderer.render( scene, portalCamera );
thisPortalMesh.visible = true; // re-enable this portal's visibility for general rendering

Yep, that fixed the issue! Thx.
