Effects with Image Magick

Some immediate effects taken from the docs.

Such an approach can be used to set lockscreens by simply taking a screenshot, using one of the effects and then using a lock manager like i3-lock which can use an image to set as lock background. Do note that the image magick commands below can take upto 2 seconds to run, so such a delay may not always be acceptable.
