def cleanup_temporary_files
  return unless cleanup_files.any?

  cleanup_files.each do |file|
    begin
      FileUtils.rm(file)
    rescue => e
      Shoes.logger.debug("Error during image temp file cleanup.\n#{e.class}: #{e.message}")
    end
  end
  cleanup_files.clear
end

#load_file_image_data(name) ⇒ Object

Why copy the file to a temporary location just to pass a different name to load? Because SWT doesn’t like us when we’re packaged!

Apparently the warbler-style path names we end up with for relative image paths don’t cross nicely to SWT, so we need to resolve the paths in Ruby-land before handing it over.
