What do such dimensions as 1*, 2* and -1 mean in BXML?
e.g., from the Table Panes page:
<TablePane.Row height="50">
<Label text="50" styles="{verticalAlignment:'center'}"/>
</TablePane.Row>
<TablePane.Row height="-1">
<Label text="-1" styles="{verticalAlignment:'center'}"/>
</TablePane.Row>
<TablePane.Row height="1*">
<Label text="1*" styles="{verticalAlignment:'center'}"/>
</TablePane.Row>
<TablePane.Row height="2*">
<Label text="2*" styles="{verticalAlignment:'center'}"/>
</TablePane.Row>

Forgive me if it's in the docs: I could not find the answer.
