I have a class which calculates a number of points (in latitude/longitude) for a hyperbel and I'd like to be able to draw the points on a GMap map. I'm using WPF and have created a UserControl and overridden the 'OnRender' method. I'm able to draw on the DrawingContext but I haven't been able to figure out how to handle zoom in/out and conversions between lat/long and screen/map-coordinates.
