Riccardo Schirone 94f303ca36 core/graph: clean code + fixes 
cons/canvas_line: split style in color and symbol

In this way you can choose to apply a color and/or a symbol (t/f/v) to a
line. This patch also changes core/graph to avoid t/f symbols in the
middle of long edges.

cons/canvas_line: fix "reversed" edge

core/graph: center current node when changing function
