FS#13745 - Add transpose (like in python pillow module) and smooth resizing in rocklua
User who did this - Ivan Romaniuk-Mikhailovsky (zoaix)

----------
I make this in my own module

  flip_rotate = function(src_img, angle, clip)
		src_width = src_img:width()
		src_height = src_img:height()
		if not angle then
			angle = 1
		end
		local func = nil
		local img = nil
		if angle == 0 then
			return src_img
		elseif angle == 1 then
			img = rb.new_image(src_height, src_width)
			func = function(_, x, y)
				return src_img:get(y, src_height - x + 1)
			end
		elseif angle == 2 then
			img = rb.new_image(src_width, src_height)
			func = function(_, x, y)
				return src_img:get(src_width - x + 1, src_height - y + 1)
			end
		elseif angle == 3 then
			img = rb.new_image(src_height, src_width)
			func = function(_, x, y)
				return src_img:get(src_width - y + 1, x)
			end
		end
    img:marshal(nil, nil, nil, nil, nil, nil, clip, func)
    return img
  end
