* Add MagickWand perf test. * Use MagickWand. * Calculate the right thumbnail dimension. * Remove magick bin file. * Add building dependencies. * Build images. * Add --no-install-recommends * Remove unused field. * Fix typo * Use uint in the worker. * Add guard * Always update apt. * Fix EncodeJpeg() with the quality * Rename the local error with a better name. * Add worker.Terminate() * Fix typo * Rebase with master and rollback the build workflow.
