[Interest] Enumerating context properties from QML

[Jérôme Godbout]

I'm not sure it will work but one might try. You might recover the object
context and maybe scan the meta object to find the properties.

*auto context = QQmlEngine::contextForObject(myObjPtr);*

Since there's no getter into the context directly. The only getter is
*contextProperty(const QString& name)*

Maybe the meta object of the context could hold some information, not sure
it will help but can give some idea.
*auto meta_obj = context->metaObject();*

Iterate on properties to see if you can extract some information out of it
*for(int i = 0; i < meta_obj->propertyCount(); ++i)*
*{*
*  auto meta_property = **meta_obj->**property(i);*

*  // check if the property hold anything of interest here
http://doc.qt.io/qt-5/qmetaproperty.html
<http://doc.qt.io/qt-5/qmetaproperty.html>*
*}*

I'm really not sure if this could extract anything from Context value but
might worth a small test. Check into the meta info, maybe something can
salvage the information (we do this to inspect particular object to debug
them but for Context, I never really tried.
