1. ESRI WKT: a dialect widely adopted by ESRI proprietary software.
2. GDAL WKT1: a dialect historically supported by the open source GDAL library.
3. WKT2:2015: as defined by ISO 19162:2015 standard specifications.
4. WKT2:2018: as defined by ISO 19162:2018 standard specifications.

• new_path: a relative or absolute pathname leading to a valid PROJ's SQLite database.

• auth_name and auth_srid identify the intended CRS.
  auth_name can be NULL, and in this case EPSG will be assumed.
• the optional argument style determines which specific WKT format should be adopted, and must be one between GDAL, ESRI, ISO-2015 or ISO-2018 (this latter being the default setting).
• the optional argument indented if set to TRUE will nicely format a multiline WKT expression, otherwise a single monolithic line lacking any white-space or new-line will be printed (the default is TRUE).
• the optional argument indentation determines how many white-spaces are to be used for indenting (only meaningful if indented=TRUE; the default values is 4).

• wkt_expr: the WKT expression to be evaluated.

• filename: the absolute or relative path leading to some Shapefile.
  Note: exactley as required by ImportSHP() filename must omit any .shp, .shx, .dbf or .prj suffix.

• Short conclusion: installing the software alone is not enough.
  The PROJ.6 private database proj.db must be properly installed as well, in order to ensure that anything runs smoothly.

1. the first place where proj.db will be searched is the same folder form where the EXE binary was initially loaded.
   Example: assuming that you are currently executing C:\myprogs\spatialite\bin\spatialite.exe
   • then an attempt will be made to connect C:\myprogs\spatialite\bin\proj.db
2. a second attempt will be made on behalf of the Public folder.
   Example: an attempt will be made to connect C:\Users\Public\spatialite\proj\proj.db
3. a third (and last) attempt will be made on behalf of the User folder.
   Example: an attempt will be made to connect C:\Users\sandro\spatialite\proj\proj.db
