nl_tokens: Compare this point with another point when the x and y values of both points are rounded . For example : [ 100 . 3 199 . 8 ] will equals to [ 100 200 ] .
pl_tokens: function ( point ) { if ( typeof point != 'object' ) { point = { x : 0 , y : 0 } ; } return ( Math . round ( this . x ) === Math . <mask> ( point . x ) && Math . round ( this . y ) === Math . round ( point . y ) ) ; }
