Test whether a circle fully lies within a polygon in TikZ
Given the following TikZ picture with an irregularly shaped polygon:
documentclass{article}
usepackage{tikz}
begin{document}
begin{tikzpicture}
path[draw=blue] (0,3) -- (5,4) -- (3,2) -- (4,0) -- (1,1) -- cycle;
node [circle,draw=none,fill=green,inner sep=0pt,minimum size=0.3cm] at (3.5,0.4) {};
node [circle,draw=none,fill=green,inner sep=0pt,minimum size=0.3cm] at (1.03,1.3) {};
node [circle,draw=none,fill=red,inner sep=0pt,minimum size=0.3cm] at (3.3,2) {};
node [circle,draw=none,fill=red,inner sep=0pt,minimum size=0.3cm] at (0.7,1.8) {};
end{tikzpicture}
end{document}
The two green circles in the picture lie completely inside the polygon, while the red ones lie partially or fully outside. Is there a way to automate that "ownership" test in TikZ? I know algorithms exist for such kind of tests, but does TikZ already provide this or similar features (e.g. tests for single points)?
