 .. probably not before renaming ST_Line_Interpolate_Point to
 ST_LineInterpolatePoint ..

 The function will be useful to interpolate along a great circle arc.

 {{{
 < pramsey> interpolate point along circle you'll have to do using a
 project
 < pramsey> not using the trick from segmentize
 < pramsey> the segmentize trick is faster, but it's not linearly
 proportional
 < pramsey> lwgeom_project_spheroid
 < pramsey> lwgeom_azumith_spheroid
 < pramsey> lwgeom_distance_spheroid
 < pramsey> probably the primitives you'll need
 }}}
