/** A process window.
*
* Clients are the name used by Awesome (and X11) to refer to a window.
*
* A program can have multiple clients (e.g. for dialogs) or none at all (e.g.
* command line applications).
* Clients are usually grouped by classes.
* A class is the name used by X11 to help the window manager distinguish
* between windows and write rules for them. A client's behavior is also
* defined by its `type` and `size_hints` properties.
* See the `xprop` command line application to query properties for a client.
*
* ![Client geometry](../images/client_geo.svg)
*
* The client's `:geometry()` function returns a table with *x*, *y*, *width*
* and *height*. The area returned **excludes the border width**.
* All clients also have a `shape_bounding` and `shape_clip` used to "crop" the
* client's content.
* Finally, each clients can have titlebars (see `awful.titlebar`).
*
* Additionally to the classes described here, one can also use signals as
* described in @{signals} and X properties as described in @{xproperties}.
*
* Some signal names are starting with a dot. These dots are artefacts from
* the documentation generation, you get the real signal name by
* removing the starting dot.
*
* Accessing client objects can be done in multiple ways depending on the
* context.
* To get the currently focused client:
*
* local c = client.focus
* if c then
* -- do something
* end
*
* To get a list of all clients, use `client:get`:
*
* for _, c in ipairs(client.get()) do
* -- do something
* end
*
* To execute a callback when a new client is added, use the `manage` signal:
*
* client.connect_signal("manage", function(c)
* -- do something
* end)
*
* To be notified when a property of a client changed:
*
* client.connect_signal("property::name", function(c)
* -- do something
* end)
*
* To be notified when a property of a specific client `c` changed:
*
* c:connect_signal("property::name", function()
* -- do something
* end)
*
* To get all the clients for a screen use either `screen.clients` or
* `screen.tiled_clients`.
