textbox(
  text,
  x = unit(0.5, "npc"),
  y = unit(0.5, "npc"),
  just = c("center", "left", "right"),
  txt_gp = getOption("txt_gp", default = gpar(color = "black", cex = 1)),
  box_fn = roundrectGrob,
  box_gp = getOption("box_gp", default = gpar(fill = "white")),
  name = "textbox"
grid.textbox(...)
