[Xerte] drawing stuff with code

[Julian Tenney]

It's very hacky, but any script in {} on the properties of the icon is
evaluated. You could maybe addDraw(myParent), then you only have one
icon in the page, and the draw is added to the page itself?

Trying to combine the text object that will be drawn on and the script
that calls the function to do the drawing.

There have been a few cases of objects doing things unexpectedly (Wasn't
a script attached directly to an interaction one of them?).
And from my mistakes in writing rlo's directly, some funny things have
happened.
Sort of like undocumented calls.

I'm trying to have a single icon I can drop on the flow line that will
contain both the drawn object and the code that will call the draw.

I doubt it possible, as SCR is probably the only one that calls the
interpreter, but I thought I'd ask.
