- \param pattern The patter that the extension should be written to
- \param in_file_extension The C string that represents the extension
-
- This function just goes through the string, and takes all characters
- and puts a [<upper><lower>] so that both are searched and shown in
- the file dialog. This function edits the pattern string to make
- this happen.
