[R] adjusting textsize and spacing in mosaic (vcd package)

[Richard.Cotton at hsl.gov.uk]

I'm trying to find a way to change the font size in a mosaic plot (the 
grid version, not the base graphics one).

Here's an example to demonstrate:
#Basic plot
library(vcd)
mosaic(HairEyeColor, shade = TRUE)

#Bad first guess: this stops the default cell colouring, and doesn't 
change the font size
mosaic(HairEyeColor, shade = TRUE, gp=gpar(fontsize=16))

#This successfully changes most of the text sizes, but not the numbers on 
the legend scale
mosaic(HairEyeColor, shade = TRUE, 
   labeling_args=list(gp_labels=gpar(fontsize=16),
      gp_varnames=gpar(fontsize=18)),
   legend_args=list(fontsize=16),
   margins=unit(4, "lines"),
   legend_width=unit(7, "lines"))

How do I change the size of the text on the legend scale?

Also, is there a way to change all the font sizes at once? 

Regards,
Richie.
