Shp edit question

[PatG]

Three questions. I have dug through the archives and the old yahoo list without success.

1) Is there a minimum and maximum size for icons?

2) What is the scale of the individual bmps used to generate the shp files? - how many inches/millimetres per pixel?

3) Is turret placement determined by game code or some other factor? - If other how do you set where a turret sits in relation to the underlying "chassis".

Thanks.

1) 89x89 pixels though a hex appears to by only 50 pixels across so icons larger than this will bleed into the surrounding hexes.
2) approximately 150 mm or 6" per pixel
3) Adjust the crosshairs in ShpEdit using the SP fix button to set the centres of rotation of the chassis and turret.
