"Objects of this class are stored in the wx.LayoutConstraint class as one of
eight possible constraints that a window can be involved in.  You will never
need to create an instance of wx.IndividualLayoutConstraint, rather you should
use create a wx.LayoutContstraints instance and use the individual contstraints
that it contains.

Constraints are initially set to have the relationship wx.Unconstrained, which
means that their values should be calculated by looking at known constraints.

The Edge specifies the type of edge or dimension of a window.

 Edges

    wx.Left 	The left edge.
    wx.Top 	The top edge.
    wx.Right 	The right edge.
    wx.Bottom 	The bottom edge.
    wx.CentreX 	The x-coordinate of the centre of the window.
    wx.CentreY 	The y-coordinate of the centre of the window. 


The Relationship specifies the relationship that this edge or dimension has
with another specified edge or dimension. Normally, the user doesn't use these
directly because functions such as Below and RightOf are a convenience for
using the more general Set function.

 Relationships

    wx.Unconstrained 	The edge or dimension is unconstrained
                        (the default for edges.)
    wx.AsIs 	        The edge or dimension is to be taken from the current
                        window position or size (the default for dimensions.)
    wx.Above 	        The edge should be above another edge.
    wx.Below 	        The edge should be below another edge.
    wx.LeftOf 	        The edge should be to the left of another edge.
    wx.RightOf 	        The edge should be to the right of another edge.
    wx.SameAs 	        The edge or dimension should be the same as another edge
                        or dimension.
    wx.PercentOf 	The edge or dimension should be a percentage of another
                        edge or dimension.
    wx.Absolute 	The edge or dimension should be a given absolute value.

"Note: constraints are now deprecated and you should use sizers instead.

Objects of this class can be associated with a window to define its layout
constraints, with respect to siblings or its parent.

The class consists of the following eight constraints of class
wx.IndividualLayoutConstraint, some or all of which should be accessed
directly to set the appropriate constraints.

    * left: represents the left hand edge of the window
    * right: represents the right hand edge of the window
    * top: represents the top edge of the window
    * bottom: represents the bottom edge of the window
    * width: represents the width of the window
    * height: represents the height of the window
    * centreX: represents the horizontal centre point of the window
    * centreY: represents the vertical centre point of the window 

Most constraints are initially set to have the relationship wxUnconstrained,
which means that their values should be calculated by looking at known
constraints. The exceptions are width and height, which are set to wxAsIs to
ensure that if the user does not specify a constraint, the existing width and
height will be used, to be compatible with panel items which often have take a
default size. If the constraint is wxAsIs, the dimension will not be changed.
