"cannot find trait `FontRef` in this scope"

[szabgab]

While trying to publish a crate using imageproc I get this error:

error[E0405]: cannot find trait `FontRef` in this scope
  --> /home/gabor/.cargo/registry/src/index.crates.io-6f17d22bba15001f/imageproc-0.24.0/src/drawing/text.rs:43:64

Very strange. After removing /home/gabor/.cargo/registry/src/index.crates.io-6f17d22bba15001f/imageproc-0.24.0/ and running cargo publish --dry-run again, the process passed.

Maybe I edited that source-file by mistake?

Thanks for checking.
