<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">This is indeed an exception. For Lambert_Conformal_Conic_2SP, the order of standard parallel is indifferent (and EPSG and ESRI don't use the same order. Same with MapInfo as far as I remember). This results in the same mathematical projection. So I've added an exception in IsSame() to accept that difference.
