+%D \macros
+%D   {positionoverlay,startpositionoverlay}
+%D
+%D As long as we're dealing with graphics it makes much sense
+%D to use the available overlay mechanism. For this purpose, we
+%D define some dedicated overlay extensions.
+%D
+%D \startbuffer[sample]
+%D \defineoverlay [sample] [\positionoverlay{sample}]
+%D
+%D \startpositionoverlay{sample}
+%D   \setMPpositiongraphic{A-1}{connectcenter}{from=A-1,to=A-2}
+%D \stoppositionoverlay
+%D \stopbuffer
+%D
+%D \typebuffer[sample]
+%D
+%D \startbuffer[graphic]
+%D \startMPpositiongraphic{connectcenter}
+%D   path pa, pb ; pair ca, cb ;
+%D   initialize_box(\MPpos{\MPvar{from}}) ; pa := pxy ; ca := cxy ;
+%D   initialize_box(\MPpos{\MPvar{to}}) ; pb := pxy ; cb := cxy ;
+%D   draw pa withcolor red ;
+%D   draw pb withcolor red ;
+%D   draw ca -- cb withcolor blue ;
+%D   anchor_box(\MPanchor{\MPvar{from}}) ;
+%D \stopMPpositiongraphic
+%D \stopbuffer
+%D
+%D We can best demonstrate this in an example, say:
+%D
+%D \startbuffer[text]
+%D \framed
+%D   [backgroundachtergrond=sample,align=middle,width=7cm]
+%D   {We want to connect \hpos {A-1} {this} word with its
+%D    grammatical cousin \hpos {A-2} {that}.}
+%D \stopbuffer
+%D
+%D \typebuffer[text]
+%D
+%D \startlinecorrection
+%D %\getbuffer[graphic,sample,text]
+%D \stoplinecorrection
+%D
+%D The graphic is defined in the following way, using some
+%D macros defined in an auxiliary \METAPOST\ module that is
+%D preloaded.

+%D \typebuffer[graphic]

+%D is set.

+%D Here the complication has to do with collecting actions
+%D for later execution. This collection is especially handy
+%D when we want to move actions to a specific layer.
+%D Such series of actions are stored in a macro (the one
+%D with the funny \type {++}) which is cleaned up after each
+%D invocation.

+%D A non graphic example of the use of positioning, is to stack
+%D text in for instance the margin.
+%D
+%D \stackposdown \inleft {some text}The text \type {some text}
+%D goes into the left margin, and \stackposdown \inleft {some
+%D more}\type {some more} as well. When they overlap, they
+%D will not touch.
+%D
+%D Here we said \type {\stackposdown \inleft{some text}}. Instead
+%D of \stackposleft \inleft {one}stacking \stackposleft \inleft
+%D {two}vertically, one can stack horizontally by \stackposleft
+%D \inleft {three}using \type {\stackposleft}.
+%D
+%D We can go in all four directions, using \type {\stackposdown},
+%D \type {\stackposup}, \type {\stackposleft} and \type
+%D {\stackposright}.
