Package mapsoft2: Information

- Drawing maps, tracks, waypoints, srtm-data:
    Fix projection setting if map boundaries can not be converted.
    Fix adjusting waypolit lable positions, avoid infinite loops.
    Fix multi-thread locking in waypoint rendering.
    Fix default track color (blue).
    Fix drawing summit labels on tiles (srtm layer).
    Use srtm_bgcolor if picture is out-of-scale
    When drawing tiled maps do not fail at empty images, return color 0
- Geodata, geo-conversions:
  - Read-only support for Polygon/MultiPolygon features in GeoJSON.
  - New alias: SU<n>N for soviet grid without zone prefix.
- Creating map references (mkref):
  - Allow floating-point arguments in --mag and --dpi options when creating a map.
  - Add --north option for --mkref=nom.
  - Set default border in "tiles" and "proj" modes.
- Vector maps:
  - Add `clip` drawing feature: set clipping for all following steps
  - Value of --clip-border setting is not changing then configuring `brd`
    step, it also affects out-of-scale filling.
  - Add `fit_patt_size` drawing option.
  - Always load patterns at original size.
  - Fix a few problems with pattern rendering.
  - Support lable scaling (import/export/rendering).
- Rendering tiles:
  - Always crop tile range to [0,0,2^z,2^z]
  - Create sub-directories when creating tiles, allow tile templates with subdirs
    (thanks to @ioctl).
  - A few optimizations for creating tile maps (thanks to @ioctl):
    do not create empty tiles, do not re-assemble old tiles in --tmap_scale mode,
    a bit faster color quantization.
- geo_nom, geo_tiles:
  - ms2nom: -W option: use WGS coordinates in calculations.
  - Fix problems with crossing lon=+180/-180 
  - Add --cover option with figure or geo-file argument (thanks to @ioctl).

- Reading/writing geodata:
  - use filename as a waypoint list name when reading waypolints from gpx or wpt,
  - fix writing Ozi map files (Projection Setup line),
  - fix reading track comments from GeoJSON.
- Geodata filtering:
  - add name parameter to --join filter,
  - add --rescale_maps and --shift_maps filters (same as in mapsoft1)
- Update documentation; add geodata_ru.htm text.
- Map rendering:
  - add --map_min_sc, --map_max_sc, --map_def_col options,
  - fix and optimize drawing of multiple maps combined in a single map list.
- ms2view: many tools for editing geodata. Interface is not finished,
  but a few operations are possible: adding/moving/deleting track points,
  adding/moving/deleting/editing waypoints, adding/deleting/editing tracks.
- Fix error handling in libtiff interface.

- GeoJSON format: add extension for writing/reading maps. Now mapsoft2
  geodata structure can be stored in json without losses.
- SRTM layer: fix a few problems: parameter dialog, tile drawing,
  coordinate calculation, srtm_width file reading. Add GeoTiff support.
- Track layer: fix error in color setting. Adding new tracks in the viewer.
- Map layer: fix handling of map lists with multiple maps, fix a few
  problems with switching different viewer projections.
- Maps menu: use {/usr/share/,${HOME}/.}mapsoft2/maps_menu.json
  instead of hardcoded list of maps.
- ms2conv: --srtm option, --htm option. --name, --comm filters.
- Rendering raster images: --add,--title,--title_size options,
  Fix paths in map-files. Fix --mag option. Fix border handling for
  multiple maps.
- MapDB: change configuration file format for MP import/export
  (similar to VMAP import/export). Fix error in geohash calculation.
  Fix label rendering (scale max_text_size properly).
- ANSI escape sequences (\n, \t etc.) and empty words ("") in all
  configuration files (in read_words).
- Avoid throwing c++ exceptions through c code (in image/io_jpeg,io_tiff),
  remove ExcludeArch: armh.
- Fix difference between 32- and 64-bit systems (in image/image_remap).
- Add ms2img program: converting raster images with mapsoft2 libraries.
