nl_tokens: Finishes the calculations on an axis . This basically just assigns the remaining space to the center region .
pl_tokens: function ( ownerContext , axis ) { var size = axis . end - axis . begin , center = ownerContext . centerRegion ; if ( center ) { center [ 'set' + axis . sizePropCap ] ( size - center . getMarginInfo ( ) [ axis . sizeProp ] ) ; <mask> . layoutPos [ axis . posProp ] = axis . begin ; } return Ext . isNumber ( size ) ? 1 : 0 ; }
