//requirements -
//must be able to transform points to a new projection
// maybe not through normal shape library
//must be able to find a random point within the shape
//
//250112 so far so good, can iterate children.
//safest thing is to establish that I can place a point as being inside or outside of a shape
//(are they closed properly!)
//If we can find points in them then we can start the main task:
//connecting parts of the SVG with rows in the spreadsheet
//maybe next first I should look at projections (to keep them happy)
//I have a map with rectangular coords,
//is easy to enough to play with the projection
// public boolean contains(RGeomElem shp)
// public geomerative.RRectangle getBounds()
// --> this is kind of hidden. why? anyway, it should be possible to use it
//another option is to use the OUTLINE of the country (as a purely geometric thing).

a- the 3D position of a point A that is to be projected.
c- the 3D position of a point C representing the camera.
O- The orientation of the camera (represented, for instance, by Tait–Bryan angles).
e- the viewer's position relative to the display surface.[1]
