Layout: Tweak documentation blurb

Being addable to a ScrolledWindow is not interesting; now that SW
auto-adds a Viewport if needed, so can DrawingArea and any other widget.

Mention GtkFixed in case the reader just wants that bit of functionality

* @Short_description: Infinite scrollable area containing child widgets
* and/or custom drawing
* @Title: GtkLayout
* @See_also: #GtkDrawingArea, #GtkScrolledWindow
* @See_also: #GtkDrawingArea, #GtkFixed
*
* #GtkLayout is similar to #GtkDrawingArea in that it’s a “blank slate”
* and doesn’t do anything but paint a blank background by default. It's
* different in that it supports scrolling natively (you can add it to a
* #GtkScrolledWindow), and it can contain child widgets, since it’s a
* #GtkContainer. However if you’re just going to draw, a #GtkDrawingArea
* is a better choice since it has lower overhead.
