minimize margins as far as possible #463

Dear @thomasp85,

first, thanks for this really cool package. And now, my problem: I would like to plot 7 trees in rows of three. It works as expected but the margin between the trees could be smaller -- resulting in less white space and hopefully larger trees in the end.

Here is my code:

grid_hgt <- pfam05199_hgt + pfam00703_hgt + pfam00331_hgt + pfam00722_hgt + pfam00295_hgt + pfam01055_hgt + pfam04616_hgt + plot_annotation(tag_levels="a",tag_prefix = "(", tag_suffix = ")") &
  theme(plot.tag = element_text(size = 12), plot.margin= unit(c(0,0,0,0), "pt"),  panel.spacing = unit(0, "cm"))
grid_hgt

and a shot of my figure. You see what I mean, right?

For all tree objects (like pfam05199_hgt), I have also used + theme(plot.margin = margin(0,0,0,0,"cm")). But this also did'nt solve my problem.

Any help is highly appreciated.

Cheers Bastian
