- image_cnt, srtm, ms2geofig: add tracing of rivers and mountain
  ridges (my old code from mapsoft1 with some improvements);
  move code for finding summits to image_cnt; fix SRTM::get_img() method
  and use it for contour and summit tracing to avoid data smoothing;
  cleanup code and tests in image_cnt.
- geom/poly_tools.h: add join_cross function (join crossing parts of a MultiLine);
  use it in vmap2 when saving fig and gpx; use it in ms2geofig when tracing steep slopes.
- image: add ImageR::get_double_range method
- srtm: fix error in deg->m conversion
- downloader: fix test for libcurl>=8.9.0 (fix altlinux.build)

- fix a few memory-handling problems (thanks to valgrind)

image:
 - Add support for reading tiled TIFF images
 - An important fix for tiled image data handling (much faster rendering)
 - Fix slazav/mapsoft2#67 error (important for new libtiff)
 - A few fixes and interface changes
image_cnt - new module:
 - Finding contours on the image, smart contour filtering
srtm:
 - Rewrite data handling and interpolation (one more time)
 - Fix data handling for much faster operation
 - Using image_cnt module
 - Using overlay data (see https://github.com/slazav/alos_overlay)
vector maps:
 - remove set_dpi command in types.cfg; set fig font size for each object separately
 - improve default label positions: move to the nearest object point; label_def_mshift option
vmap_data:
 - types.cfg: adjust fig font size, add label_def_mshift for some objects
 - render.cfg: tune fonts for summits and passes
 - always use UTF8 encoding in fig files
 - vmaps_wp_update: use single wpasses.cnv
ms2geofig program:
 - apply --cnt_minpts option only to closed contours
 - new contour finding; add cnt_vtol, scnt_vtol options; remove smooth option
 - --add_comm option (adding additional comments to new fig objects)

A few bug fixes:
- err: fix problems with NaN values and with multiple evaluations in assert scripts
- geom/line_walker: avoid NaN values for lines with repeated points
- fig: fix scaling/shifting
- srtm: fix error in find_peaks(), fix error with getting points between tiles
- vmap2gobj: fix problem with short_expand feature applied to zero-length lines
- vmap2: optional scale argument to fig_pic command in types file
- viewer/gobj_multi: set trivial cnv in constructor, check for NULL cnv

- 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
  layers when low-resolution picture is needed. Remove automatic
  interpolation of holes. Use overlays: manual creation/interpolation of
  holes and saving this information. Fix error with drawing of a
  semi-transparent srtm layer. Optimize contour finding.
- Rewrite GeoTrk class: now it is MultiLine<double,GeoTpt>
  instead of GeoTpt array with segment start flags. Massive
  changes in all code working with tracks.
- Add vxi module (VXI-11 interface)
- build system:
  - preliminary check for pkg-config libs.
  - remove support for local pkg-config files
  - PROG_DEPS variable - dependence on executables
- geom:
  - Line/Multiline definition with separate coordinate and point types
    MultiLine<double,GeoTpt>
  - Point, Rect, Line, Multiline: divide/multiply by point
  - Line, Multiline: npts method
  - MultiLine: add_point, add_segment, del_last_point methods
  - poly_tools.h: fix a mess with 2d/non-2d functions, use arbitrary
    distance functions (for using with GeoTrk)
  - poly_tools.h: poly_cross_2d: find crossings of two closed lines
- geo_data/filters: add --trk_reduce_acc, --trk_reduce_num options
- geo_data/geo_utils.h:
  - add geo_length_2d function for Line and MultiLine
  - add geo_bearing_2d function
- fig: write fractional font size
- downloader: set log_level via options; change default 0 (no messages)
- ocad: rewrite code, but still do not include it in vmap system
- vmap2: add dpi setting in type configuration (affects only font size in fig output)
- image:
  - support for 64/48 bit images
  - change internal representation of IMAGE_1 and IMAGE_24 formats
  - fix memory handling
  - support for PNM format 48/24/16/8/1-bit images
  - add 64/48 bit support for tiff format
  - a few image filters (some code transferred from me ph_scan repo):
    image_invert, image_crop, image_autocrop, image_autolevel, image_ir_undust
- a few modifications in vmap-data
- rewrite ms2xyz program,
  - --ref <trk> - calculating distances along a reference track
  - --break segment - restart calculation on every segment
- Add new filters to ms2img program. Now I'm using it to process images
  after film scanning: cropping, color levels, removing dust with IR channel.
