If enabled, the specified display will be automatically resized to new
sizes to conform constraints in next cases:
.IP \[bu] 2
The specified display is resizable, not maximized and is not in
fullscreen mode.
.IP \[bu] 2
If the appropriate current display size (width or height) is less than
the value of constraint.
Applied to minimum constraints.
.IP \[bu] 2
If the appropriate current display size (width or height) is greater
than the value of constraint.
Applied to maximum constraints.

Constrains are not applied when a display is toggle from windowed to
maximized or fullscreen modes.
