Enable edge tiling when dropping windows on screen edges

If enabled, dropping windows on vertical screen edges maximizes them vertically and resizes them horizontally to cover half of the available area. Dropping windows on the top screen edge maximizes them completely. 'smart'

Window placement behavior

Metacity's default window-placement behavior is smart (first-fit), similar to behaviors in some other window managers. It will try to tile windows so that they do not overlap. Set this option to "smart" for this behavior. This option can be set to "center" to place new windows in the centers of their workspaces, "origin" for the upper-left corners of the workspaces, or "random" to place new windows at random locations within their workspaces.
