title: Python FPDP multi_cell just returns a blank
body: <p>I am trying to use the multi_cell function in a project using FPDF in Python.</p>
  
  <p>However every time I call it I just get a blank space where the cell should be. If however I call cell() it displays the cell. See examples below. Anyone got an idea what is going on here?</p>
  
  <p>Blank Space with:</p>
  
  <p>pdf.multi_cell(25,cell_height,ticket_no,1,0,"J",1)</p>
  
  <p>Cell populated with data with </p>
  
  <p>pdf.cell(25,cell_height,ticket_no,1,0,"L",1)</p>
