Add `${FSLEYES_SITE_CONFIG_DIR}` as a place for colour maps and lookup tables
- Add the ability to store colour maps and lookup table files in a site-specific configuration directory, which can be set by a
${FSLEYES_SITE_CONFIG_DIR}
environment variable. Contributed by Rob Reid at https://github.com/pauldmccarthy/fsleyes/pull/121. - Change the way that FSLeyes layouts are stored - they are now saved as plain-text files in
<settings-dir>/layouts/
, or${FSLEYES_SITE_CONFIG_DIR}/layouts/
. - Default command-line arguments can now be stored in
${FSLEYES_SITE_CONFIG_DIR}/default_arguments.txt
. If<settings-dir>/default_arguments.txt
exists, it will take precedence.
