#' Lattice Theme
#'
#' A theme for use with lattice graphics.
#'
#' @param bw whether color scheme should be "black and white"
#' @param lty vector of line type codes
#' @param lwd vector of line widths
#' @param ... additional named arguments passed to
#' [trellis.par.set()]
#'
#' @return Returns a list that can be supplied as the `theme` to
#' [trellis.par.set()].
#' @note
#' These two functions are identical. `col.mosaic` is named
#' similarly to [lattice::col.whitebg()], but since more
#' than just colors are set, `theme.mosaic` is a preferable name.
