Return a mesh of points covering the surface or volume of a Region

but no axis values are returned and all other parameters are ignored. If not zero, the
supplied value should be the length of the second dimension of the "
points"
array. An
error is reported if the number of points in the mesh exceeds this number. "
points"
array. An error is reported if the
number of axes in the supplied Region exceeds this number. "
[maxcoord][maxpoint]"
, in which to return the coordinate values at the mesh
positions. These are stored such that the value of coordinate number "
coord"
for
point number "
point"
is found in element "
points[coord][point]"
. An error is reported if the Region is unbounded.
If the coordinate system represented by the Region has been changed since it was first created, the returned axis values refer to the new (changed) coordinate system, rather than the original coordinate system. Note however that if the transformation from original to new coordinate system is non-linear, the shape within the new coordinate system may be distorted, and so may not match that implied by the name of the Region subclass (Circle, Box, etc).
If the Region defines an area within a SkyFrame that traverses zero longitude, the returned positions will be normalised to avoid jumps of 2.PI radians in longitude (i.e. it will include longitude values less than zero or greater than 2.PI).
