MapWinGIS.tkMapColor.Transparent is white not transparent as it hides underneath objects.

Reviewing it before 4.9.3 Beta release: it was noticed before indeed. In the current trunk it's actually commented:
/*Transparent = 0x00FFFFFF,*/ // removed, alpha channel is set through different set of properties in API, so it's problematic to support this constant
I believe it was commented somewhere started from v4.9. In most cases transparency can be set through a dedicated property, like ShapeDrawingOptions.FillTransparency, ShapeDrawingOptions.FillVisible. If you experience problems with settings it in particular cases please let me know. We can consider adding support for this constant but it can be misleading, as it's not possible to set transparent map background for example. So the issue will most likely reemerge.
