your implementation of Intersect() can lead to an invalid envelop (a min > max) if the intersection is null. You should reset all minx,maxx,miny,maxy to 0 in that case.

I don't see the usefullness of void Intersect( double dfX, double dfY ) (I know there's an equivalent method for Merge(), but for intersect I'm more skeptical)
