\horizontal_rectangle

Description 

Operator \horizontal_rectangle defines four new edges associated to four vertices named by the operator parameters (symbols). Edges are built circularly taking two consecutive symbols. The first symbol of the parameter list binds the upper left corner of the square. Second symbol is linked to the upper right corner, the third one names the lower right corner and the fourth is associated to the lower left vertex. The type of the four edges created is border. A fifth parameter is added, it gives the ratio between width and height of the rectangle. A possibility exists to specify a well known paper format like `dollar' or `A' (ISO format: $\frac{1}{\sqrt{2}}$). Numeric ratio is given as a percentage, 200 means a rectangle as taller as a square and twice wider. If the ratio value is lesser than 100, a horizontal rectangle is still defined with a width equal to the normal square size but the height is reduce to fit the ratio.
This operator should only appear within a step block.

Usage

  \horizontal_rectangle(a, b, c, d, dollar); % a horizontal dollar paper 
  \horizontal_rectangle(A, B, C, D, 200);   % 1x2 double square size on X
  \horizontal_rectangle(A, B, C, D, 50);    % 1x2 half square size on Y

Formal structure

  \horizontal_rectangle(VERTEX_1, VERTEX_2, VERTEX_3, VERTEX_4, RATIO);
  \horizontal_rectangle(VERTEX_1, VERTEX_2, VERTEX_3, VERTEX_4, PAPER_TYPE);
