#' The theme in compliance with the INBO style guide version >= 2015.
#'
#' @inheritParams ggplot2::theme_gray
#' @param transparent Make backgrounds transparent.
#' `FALSE`: all backgrounds are white, `TRUE`: all backgrounds are transparent.
#' You can pass a vector to transparent.
#' In that case, it will check whether the values `"plot"`, `"panel"` and/or
#' `"legend"` are present.
#' The according items will be transparent.
#' Transparent panel will use grey instead of white grid lines.
