[flexcoders] Why don't horizontalCenter and verticalCenter work with Spark ColumnConstraints?

[RobertTr]

Here's code that splits the screen into two columns, left and right. Then it
puts a box in each column and attempts to center them. The horizontalCenter
and verticalCenter properties are ignored:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"; 
                           xmlns:s="library://ns.adobe.com/flex/spark" 
                           xmlns:mx="library://ns.adobe.com/flex/mx"
                           backgroundColor="blue">
        <fx:Declarations>
                <!-- Place non-visual elements (e.g., services, value objects) 
here -->
        </fx:Declarations>
        <s:SkinnableContainer id="mainContentArea"
                         top="100" bottom="100"
                         backgroundColor="red">
                <s:layout>
                        <s:ConstraintLayout>
                                <s:constraintColumns>
                                        <s:ConstraintColumn id="col1" 
width="{width/2}" />
                                        <s:ConstraintColumn id="col2" 
width="{width/2}" />                              
                                </s:constraintColumns>                          
        
                        </s:ConstraintLayout>
                </s:layout>
                <s:BorderContainer id="greenContainer"
                                                   backgroundColor="green"
                                                   width="400" height="300"
                                                   horizontalCenter="col1:0"
                                                   verticalCenter="0">
                </s:BorderContainer>    
                <s:BorderContainer id="yellowContainer"
                                                   backgroundColor="yellow"
                                                   width="200" height="150"
                                                   horizontalCenter="col2:0"
                                                   verticalCenter="0">
                </s:BorderContainer>            
        </s:SkinnableContainer>
</s:Application>
