[birt-dev] Checkin: Bugzilla#159970 - Not able to change the chart size

["Yulin Wang" <yulin.wang@xxxxxxxxxxx>]

- Summary:
Not able to change the chart size using event handlers

- Bugzilla Bug (s) Resolved:
159970

- Description:
User could write simple API code to resize charts.
This is how:
1. open "script" tab and click the root node (report name) in outline view
2. select "beforeFactory" method in editor's combo
3. write code like this: this.getReportElement(CHART_NAME).setHeight("400pt")
Note that some relative dimension units like "px" or "%" are not supported here.

Fixed by overriding IReportItem methods to update internal chart size when resizing extended item.
