# Add a border to the outside of the image
#
# image.border(options = {})
#
# Use the following keys in the +options+ hash:
#
# * +size+: Width of the border on each side. You can use a 2 dimensional value ('5x10') if you want
# different widths for the sides and top borders, but a single integer will apply the same border on
# all sides.
#
# * +color+: the color of the border. Use an RMagick named color or use the +color+ method in
# FlexImage::Controller, or a Magick::Pixel object.
#
# Example:
#
# @photo.operate do |image|
# # Defaults
# image.border(
# :size => 10,
# :color => 'white' # or color(255, 255, 255)
# )
#
# # Big, pink and wide
# image.border(
# :size => '200x100',
# :color => color(255, 128, 128)
# )
# end
