In Wolfenstein 3d, all objects are texture mapped squares with normals
perpendicular to the vertical.  Some people refer to the viewing
of rectangular images with view direction not parallel to the
surface normal as perspective mapping.
I believe that the term 'perspective mapping' originated from
paint programs like delux paint which allow you to take an image
and map it onto a plane viewed from any angle.  It really should not
be used out of that context.
Texture mapping is the process of making an object look more realistic
by filling it with an image rather than flat colour.  Just another
step along the route from wire frame to solid 3d to....
