Remarks

ExpansionIndicatorSize, ExpansionIndicatorPadding, and Indent are closely related and the behavior of these three properties depends on the ViewStyle.

When ViewStyle is Standard, the actual indentation of the nodes in the tree will be the Indent property, unless the Indent is too small. If the Indent property value is too small to fit the ExpansionIndicatorSize and it's padding, then it will be enlarged to fit.

When ViewStyle is Vista, the Indent property is ignored, and the indentation is automatically calculated to fit the ExpansionIndicatorSize and ExpansionIndicatorPadding.

Note: When using Themes, the expansion indicators are drawn using the Windows Theme API. Themed expansion indicators have a maximum size of 9x9 and must be square (not rectangular). Specifying a larger size will leave extra padding around the expansion indicator, but the drawn image will not get any bigger.
