GM_ConvertCoordGroundToPixelWithOrientationDouble

Convert a coordinate between the current projection and a pixel coordinate. The conversion space can be either the last drawn coordinate space or the caller can provide the coordinate space to work in.

Note: The only time that you should need to call this function is if you want to do a coordinate conversion in a different orientation than what has been set globally with GM_SetOrientation .
