What is the point of reserving a space or window when creating a figure using the picture environment? I mean if I have the following setup:
\setlength{\unitlength}{0.5mm}
\frame{
\begin{picture}(80,60)(0,0)
\put(0,0){\circle*{3}}
\put(-10,-10){\circle*{3}}
\put(180,-10){\circle*{3}}
\end{picture}}
I will get this result
----------------------------------------------------- This simply means that I can draw elements outside the boundaries of that space, so why does it exist in the first place? In other words, what does it represent, or why it's in the background?
\frame{
should have a%
as you ar framing a space to the left of the picture but not the right
