@kbr and others, i'm not sure if this comment and related code could be removed
for supporting TEXTURE_WRAP_R.

[piman, 2015/05/11 21:39:34]

FYI on ES, cube maps are always seamless regardless of wrap modes.

[Zhenyao Mo, 2015/05/11 23:23:44]

Yes, remove it.

-  // GraphicsContext3D.cpp is strictly necessary to avoid seams at the
-  // edge of cube maps, and, if it is, push it into the GLES2 service
-  // side code.
-  if (pname == kTextureWrapR) {
-    return;
-  }
   gl_->TexParameteri(target, pname, param);
 }
