Tinderbox uses the same units for a number of Map view related attributes:
- icon sizes
- map co-ordinates
- viewport positioning co-ordinates
- container title bar depth (vs. viewport)
- fill configuration
When used for position, attributes use two unit values to give Map co-ordinates.
Whereas co-ordinate values may be positive of negative, for basic sizing positive values should always be specified.
Note: the following applies to v5.x or earlier and will likely not be accurate with 4k displays. To map Tinderbox units to pixels use this formula: (N*36)-4 where N is the map unit figure. Thus 3 map unit = (3*36)-4 = 104 pixels. The '-4' adjustment is because Tinderbox allows a 2 pixel 'outer' buffer all round. As this buffer area never overlaps during automatic spacing of notes, it ensures at least a minimum 4 pixels gap between map icons.
