Some instruction for generating new OSMAND map icons from .svg files with the OsmAnd-resources\icons\tools

1. place new .svg files in a resonably named svg source folder \icons\svg\source_folder_name\

2. open \icons\tools\generatedpng.sh in editor and add or uncomment (delete initial # sign) a line pointing to the source_folder_name, 
   e.g.: genMapIconsStdSize 'source_folder_name' '#' x2
   
3. place a copy of rsvg-convert.exe (https://github.com/miyako/console-rsvg-convert) into the C:\Windows\System32\ folder

4. run generatedpng.sh in git bash

5. new files are generated from the new .svg files: 
   a working copy of the svg files in \icons\vd\svg\source_folder_name_file_name.svg
   four different scales of png files in corresponding subfolder in \icons\png\...\source_folder_name_file_name.png
   a xml version of the svg file in \icons\vd\map\source_folder_name_file_name.xml
   
6. open \icons\tools\sortfiles.sh in editor, save a new working copy with new filename and add in it required icon_alias command lines for all new files, 
   e.g.: icon_alias target_name_in_app_render_xml original_source_folder_name_file_name
   you can comment-out or erase all other and unrequired alias command lines in order to significantly speed up the very long copying process
   
7. in case the target filenames already exists, you need to delete the existing .png files manually in all four target folders (because overwriting of existing .png files is prevented in sortfiles.sh)
   \rendering_styles\style-icons\map-icons-png\...\target_name_in_app_render_xml.png
   
8. rund sortfiles.sh in git bash (install bash beforehand, if not already available)

9. if available, the following files are copied to \rendering_styles\style-icons\... folders
   four different scales of png files in corresponding subfolder from \icons\png\...\source_folder_name_file_name.png  to \rendering_styles\style-icons\map-icons-png\...\mm_target_name_in_app_render_xml.png
   a xml version of the svg file from \icons\vd\map\source_folder_name_file_name.xml to \rendering_styles\style-icons\map-icons-vector\h_target_name_in_app_render_xml.xml
