mini_magick 5.1.0

on Ruby Gems

New cli_env configuration was added for setting extra environment variables for every CLI command:

MiniMagick.configure do |config|
  config.cli_env = { "MAGICK_MEMORY_LIMIT" => "128MiB" }
end

New graphicsmagick configuration was added for telling MiniMagick to use GraphicsMagick instead of MiniMagick:

MiniMagick.configure do |config|
  config.graphicsmagick = true # prepend all commands with "gm"
end

Previously, the recommended approach was setting MiniMagick.cli_prefix = "gm", but that doesn't work when ImageMagick 7 is installed, as in that case MiniMagick will try to prepend magick on top of gm.
