- Improve support for tiled maps. Add MBTiles support
  Now ms2view and ms2render can use mbtiles as input map format,
  ms2render can render tiles directly to mbtiles.
- Support for Finnish standard maps (e.g. V51) and Finnish grid.
- Rewrite map rendering scripts (vmap_data/scripts). Direct rendering
  to mbtiles. Update map data. Important fix of Garmin TYP file.
- Add ms2view desktop (#70, thanks to sikmir)
- Fix and improve contour rendering and smoothing (image_cnt module, ms2geofig program)
- vmap2:
  - allow larger type numbers (3-bytes instead of 2)
  - new features for rendering vmaps: "grid_labels", "draw_pos fill"
  - add a few functions for custom map filtering
  - support for objects types > 0xFFFF
- write_geoimg:
  - mbtiles support
  - default background: transparent for tiled maps, white for others
  - add --fillcolor, --zfill, --swapy options
- viewer:
  - Objects can check drawing range, in advance. This is used in
    tile rendering to avoid reading/creating tiles which are not needed
    (slazav/mapsoft2#61).
  - Get rid of prepare_range mechanism. It was an attempt to do
    parallel downloading of tiles, but it ignored caching and did a lot more
    additional work. Now tile downloading is requested one by one, during
    rendering.

- Rewrite SRTM interface (work is not finished). Support for data with
  different resolution, do not use srtm_width.txt file (note that ALOS has
  different resolution at high latitudes, previously it was just
  rescaled). Simplify interpolation code, allow switching between nearest,
  linear, cubic interpolation. Do not use interpolation in graphical
