Hi all,

The docs for IGraphicTracker.SetTransparency include the line "This is used only in 2D mode and only if the graphic's symbol supports ISymbolEffects", which is all well and good except ISymbolEffects...doesn't seem to exist. ESRI's search engine turns up nothing, and Google only returns links to the API reference for .SetTransparency.

Using .SetTransparency in code doesn't seem to do anything. Does anyone know:
a) if this interface actually exists, or
b) it's possible to use transparency in the GraphicTracker, and if so....how?
