Hi
The general "evolution" of grid.*() functions (that I have written)
have
tended towards the grid.polyline() style ...
grid.*(...) {
grid.draw(*Grob(...))
}
With my thinking at least heading towards: if you are calling grid.*(),
then you want to actually draw something; if you want to just create a
description of something to draw, then you want to call *Grob().
In other words, I have come to view the 'draw' argument to grid.*() as
redundant.
That reflects how I use 'grid', so I may be unaware of an important
counter argument.
