Some speed tests for qx.ui.basic.Atom. Please regard, that many of things in the finished page are modified on the already created and visible qx.ui.basic.Atom instances. This is not a good example in scripting qooxdoo. It's always faster to configure a instance of qx.ui.core.Widget completely, before add it to the qx.ui.core.ClientDocument or any other visible parent qx.ui.core.Widget.
