it is easiest to draw the shapes in Dia itself and then export them to the
.shape file format
there is a tag
<aspectration value=fixed />
that is roughly it, i dont memorise these things.
best to export a .shape file or look at some of the existing files.
there is a text object, agian with no Dia files available in front of me
at the moment on my crappy dialup connection i suggest you look at the
existing files. (take a look at the SDL sheet and the comment {
object/shape which i do actually remember has some sort of text widget).
