 That might have been case of `r.out.tiff` too. This goes outside of this
 ticket, but now I wonder what is the relation of `r.out.png` to r62524.
 Why was `r.out.tiff` moved to addons and `r.out.png` left in core? Maybe
 dependency considerations?

 In any case, the point of both `r.out.png` and `r.out.tiff` is an easy
 interface at this point (since GDAL will be always present), assuming that
 the differences in outputs are addressed. So than `r.export.png` makes
 more sense for 8.0 than keeping `r.out.png` around.
