Last change on this file since 1724 was 1722, checked in by stoecker, 15 years ago

Large rework in projection handling - now allows only switching and more specific projections
TODO:

  • allow subprojections (i.e. settings for projections)
  • setup preferences for subprojections
  • better support of the new projection depending world bounds (how to handle valid data outside of world)
  • do not allow to zoom out of the world - zoom should stop when whole world is displayed
  • fix Lambert and SwissGrid to handle new OutOfWorld style and subprojections
  • fix new UTM projection
  • handle layers with fixed projection on projection change
  • allow easier projection switching (e.g. in menu)

NOTE:
This checkin very likely will cause problems. Please report or fix them. Older plugins may have trouble. The SVN plugins
have been fixed but may have problems nevertheless. This is a BIG change, but will make JOSMs internal structure much cleaner
and reduce lots of projection related problems.
  • Property svn:eol-style set to native
