WCPS_Support clip() with curtain on 3D+ coverage with WKT linestring and polygon

[Bang Pham Huu]

c (coverage expression) should always be at least 3 dimensional.

clip(c, curtain(projection(arg1), polygon((arg2)) ) ),
clip(c, curtain(projection(arg1), linestring(arg2) ) ),

with arg1 is the list axis labels belonging to c (e.g: c has 3 axes: lat, long, time, then argr1 is a pair of 2 axis labels: e.g: lat, long or lat, time,…).

and arg2 is a list of vertices (each vertex contains 2 coordinates on the axes which are listed in arg1), e.g: arg1 is Lat, Long, then arg2 is: -90 30, 20 60, 90 130, -90 120,…
