growPriorityProperty

On a scale of 0..1, if this Node's parent has extra space compared to its preferred size, how much extra space should be give to this Node relative to its siblings?

0 = Never stretch. 1 = Take as much space as possible.

e.g. If two children have a growPriority of 1, and the parent's allotted size is 12 pixels wider than the children's width, then both will be given an extra 6 pixels.

e.g.2 If one child has a priority of 1, and the other has a priority of 0.5, then the 12 pixels will be shared in a 2:1 ratio i.e. child#1 gets 8 pixels extra, and child#2 gets 4.

The default is 0. So Nodes tend not to grow beyond their preferred size.
