Allow drawing of basic shapes (lines, triangles, ... ) on MapControl in a 3d layer
Let us draw non static basic shapes on the MapControl over the 3d view but not stuck to the terrain. Shapes that can be changed anytime needed and with altitudes different to the ground level.
Something like: https://i.stack.imgur.com/wjzfc.png

This is mostly possible now. You can position a 3D model at an arbitrary lat/long/alt and orientation and update it as you see fit. If the model itself needs to change, you will have to add/remove which is a bit slower.
