Add a sense of 'height'. Rockers, aircraft, etc.

[stefanhendriks]

Ie, rockets from an ornithopter are fired 'from above' and should go 'down'. The illusion of height can be given by adding a shadow (which is always the 'real' position) and drawing the rocket 'above' it.

The same goes for the air units, the shadows are fixed now and should be more flexible. For carry-alls this will give more of an illusion to 'pick up' a unit by 'going down'.

TODO

• [ ] make rockets go up when launched from ground unit & down when impacting (slight movement for small rockets, the deathhand has the most height as it has to go over the whole map)
• [ ] carry-all will go 'down' (near shadow) when picking up a unit and 'lift off' when bring that unit away
• [ ] Frigate starts 'high' and will go down to starport. (descend when at starport?)

I comment here, as it is really close to this. To give better impress of height, draw air units at "zoom x1,1" when on "non-passable cell" and draw it at "zoom x0,9" when picking or enter/exit a structure. Can be applied to rocket when fired and before explose with i.e a degraded from 0,9 >1,1 > 0,9
