imagemagick needed to convert gif to png in compiling to pdf #387

Run make clean pdf on MacOS Monterey
At a point gifs cannot be converted to pdfs
```
convert ./04/glslEditor-01.gif ./04/glslEditor-01.png
/bin/sh: convert: command not found
convert ./04/glslViewer.gif ./04/glslViewer.png
/bin/sh: convert: command not found
convert ./04/glslEditor-00.gif ./04/glslEditor-00.png
/bin/sh: convert: command not found
convert ./04/glslGallery.gif ./04/glslGallery.png
/bin/sh: convert: command not found
```
This suggests it cannot find convert command as stated. Dig a little digging and found that it is actually found in some tool called imagemagick. Can this caveat be included in the tutorial in some way for people who might no little about the process? Given that this is not a minor point in the grand scheme of things I would understand if this is not deemed to be a priority

Reproduced on macOS Ventura. GIFs left unconverted, replaced with black boxes. brew install imagemagick fixed it. Thank you OP.
