jsinterop: GWT app as a widdget: default script injection fails.

Hi,

This issue has been discussed before https://github.com/gwtproject/gwt/issues/9264

Here is the problem in my own words:

When a script is injected GWT has the option to inject it in the TOP_WINDOW ($wnd) or in the iframe window where GWT code is located normally.

Case 1: Insert in $wnd

Everything works but the page is polluted with the scripts you inject. This is not a problem when the GWT application controls the whole page. It is however a problem when GWT program is loaded as part of a page (Widget). Then all kind of problems may arise due to javascript libraries clashing.

Case 2: insert in iframe window (default)

The script is loaded but jsinterop assumes that the scripts are loaded in $wnd which is not true.

Question:

Is it possible to
1) add a compile time flag in jsinterop that will not prepend $wnd in all global objects defined by the script ...OR...
2) add a namespace JsPackage.LOCAL (as opposed to JsPackage.GLOBAL) option that does not imply $wnd ...OR...

3) do something that fixes the problem somehow!
