New developement snapshot.

[Stacho Mudrak]

So current version of therion should support centerline with LRUD in map editor. As usually - it is implemented easiest way for programmer :) with minimal changes in current interface. So how it works:

1. Therion supports new map format export - xvi (xtherion vector image).

2. XTherion can load xvi images into backgroud, as any other bitmap image.

There are some special bindings for vector images - e.g. if you insert point on station, type and station name are automatically set.

When exporting xvi images - they are exported in 100dpi in layout-scale. Grid spacing is also taken from layout X grid-size.

Waiting for feedback and comments :)
