Fields in jpicedt.graphic.model declared as PicVector
`protected PicVector` | `PicParallelogram.l2rVec` "l2rVec" is a vector pointing from P_BL to P_BR (or equally, from P_TL to P_TR) "b2tVec" is a vector pointing from P_BR to P_TR (or equally, from P_BL to P_TL) These two vectors simply define a convenient parallelogram's basis, and are updated by a call to updateParalleloBasis().
