The provider for "Lambert Conic Conformal (West Orientated)" projection (EPSG:9826).
In this projection method, the x values increase toward West. However, the projection
is defined in such a way that the sign of x values are reversed before to apply the
"false easting" translation. As a consequence of this operation order, despite its
name the "false easting" is effectively a "false westing" (FW) parameter.
See §1.3.1.3 in Geomatics Guidance Note number 7, part 2 – April 2015.
In Apache SIS implementation, this operation method does not reverse the sign of
x values because all our map projection "kernels" go from (longitude, latitude) in degrees
to (easting, northing) in metres by definition. The sign reversal is applied later, by examination of
axis directions in CoordinateSystems
