-<h2>LayoutAnchors</h2>
- A class that implements Delphi's Anchors with wxLayoutConstraints.
-<p>
- Anchored sides maintain the distance from the edge of the
- control to the same edge of the parent.
- When neither side is selected, the control keeps the same
- relative position to both sides.
-<p>
- The current position and size of the control and it's parent
- is used when setting up the constraints. To change the size or
- position of an already anchored control, set the constraints to
- None, reposition or resize and reapply the anchors.
-<p>
- Examples:
-<p>
- Let's anchor the right and bottom edge of a control and
- resize it's parent.
-<p>
-<pre>
- ctrl.SetConstraints(LayoutAnchors(ctrl, left=0, top=0, right=1, bottom=1))
-
- +=========+ +===================+
- | +-----+ | | |
- | | * | -> | |
- | +--*--+ | | +-----+ |
- +---------+ | | * |
- | +--*--+ |
- +-------------------+
- * = anchored edge
-</pre>
-<p>
- When anchored on both sides the control will stretch horizontally.
-<p>
-<pre>
- ctrl.SetConstraints(LayoutAnchors(ctrl, 1, 0, 1, 1))
