vanishing point - setup
three points and slope
3p and horizon
draw endpoints
make slope and hypotenuse for all 3 sight lines
get correct position for endpoints
draw guide lines for first three vertexes!!!
i mean vertices!!!
fix accidental shifting
bold edges and mute guides
keep log of vertex
add documentation for current vanishing point
vanishing 0.6.0 - aww yeah point slope form mid vertex
vanishing 0.6.1 - color code mid vertex
vanishing 0.7.0 - get edges and additional guide lines
vanishing 0.8.0 - add final vertex
