Added a "Multi Line" checkbox in the Legend_Tester example at the Features Demo to test this.

- In GDI it seems to never do any MultiLine; we recommend moving to GDIPlus since we don't have plans to continue improving GDI.

- In GDIPlus, having multiple series with multiline text in their titles, all teh text is drawn in a single line and a blank space is drawn at the position of the sLineBreak.

- In GDIPlus, having a single series, and disabling CheckBoxes for he legend, the texts are drawn in multiple lines but the items height isn't correctly calculated.
