Config variables

The configuration is stored in an INI file called pd.ini, which is by default in the following locations:

• On Windows: next to pd.exe if the folder is writable, home directory (%APPDATA%/perfectdark) otherwise
• On Linux: home directory (~/.local/share/perfectdark), unless there was already a pd.ini next to the executable

The file generally follows INI file syntax and consists of the following sections.
