title: Fixing spacing issue with annotations in cowplot/patchwork
body: <p>I'm trying to combine several figures drawn in PowerPoint into a panel, using patchwork, cowplot, magick. However, I always feel that the distance between the annotation and the actual figure is too big, and I'm struggling to find a way that minimises the distance.</p>

  <p>Is there a way to fix this issue?</p>
  <p>Here's is my code.</p>
  <pre><code>library(patchwork)
  library(cowplot)
  library(magick)
  
  # You can test with any other image, so the code should be reproduceable
  design &lt;- &quot;./design.png&quot;
  courses &lt;- &quot;./courses.png&quot;
  
  # here I draw the figure using draw_image
  design &lt;- ggdraw() + draw_image(design,   x = 0,
                                  y = 0)
  
  courses &lt;- ggdraw() + draw_image(courses)
  
  design / courses + plot_annotation(tag_levels = 'A')
  
  </code></pre>
