*_mode_* scaling not working well for imported fonts

[davidhodge931]

Some other registered fonts look normal at 17 - and then this screws up margins etc

Renmove from sub-text elements:

• size = base_size
• colour = base_colour

    theme(
      axis.ticks.length = grid::unit(11 / 3, "pt"),
      legend.spacing = grid::unit(11 * 1, "pt"),
      legend.spacing.y = grid::unit(11 * 1.5, "pt"),
      legend.key.size = grid::unit(11 * 1.75, "pt"),
      legend.key.spacing.x = grid::unit(11, "pt"),
      legend.key.spacing.y = grid::unit(11 * 0.33, "pt"),
      panel.spacing = grid::unit(11 * 2, "pt"),
    )

Solution = make base_size only control text size elements. All other margins, spacing etc are fixed at the default 11 values
