AlignmentPoint
is an option which specifies how objects should by default be aligned when they appear in Inset.

If obj has AlignmentPoint->opos, then Inset[obj, pos] is equivalent to Inset[obj, pos, opos]. »

	{x,y}	ordinary coordinates in a plot
	Scaled[{x,y},...]	scaled coordinates from 0 to 1
	ImageScaled[{x,y},...]	scaled coordinates from 0 to 1 across a whole image
	Offset[{dx,dy},...]	absolute offset in printer's points
	Center, etc.	{Center, Center}, etc.

y coordinates can be numbers, Automatic or Top, Center, Bottom, Baseline or Axis.

Axis corresponds to the position of the axis in a plot, or the center line in typeset text.
