test example

TDownSamplingFunction slightly changed between v2013.08 and v2013.09 making the function not to correctly update the number of values to display when zooming or resizing the form.

See the project attached.
If you zoom on the form, the charts below should show more values than they do, and refreshing the function datasource doesn't change it (refresh button on the example).

In v2013.08 the refresh button made this example to work fine.
