Mike,

All of the zoom* methods are but convenience methods, mainly to turn
image click input into new map extents.  The essence of zooming is
setting the map extent.  Look in mapscript/swiginc/mapzoom.i for the C
code of the zoom* methods.  Some of this could be adapted to your
needs.

cheers,
Sean
