title: Shadowed text without knowingly doing it using python-pptx. How to remove it?
body: <p>I am generating a pptx slide with textboxes using python-pptx module. I am able to generate four textboxes with some text formatted to my liking. However, the text is always formatted with shadowing, where I do not want any. I have been searching the documentation but I cannot seem to find any reference of shadow formatting. The code I have been using is below.</p>
  <pre><code>import pptx
  from datetime import datetime
  import pandas as pd
  
  #Colour Definition
  black = (0, 0, 0)
  Purple = (91, 43, 130)
  
  #Presentation Information
  pptTitle = 'Title'
  pptSubtitle = 'Subtitle'
  author = 'Name'
  date = datetime.now().strftime('%B %d, %Y')
  
  prs = pptx.Presentation()
  
  slide = prs.slides.add_slide(prs.slide_layouts[6])
  prs.slide_width, prs.slide_height = pptx.util.Cm(33.867), pptx.util.Cm(19.05)
  
  titleFormat_df = pd.DataFrame.from_dict({
    2: [pptTitle, pptx.util.Pt(36), Purple, pptx.enum.text.MSO_ANCHOR.BOTTOM, pptx.util.Cm(1.27), pptx.util.Cm(3.19), pptx.util.Cm(31.33), pptx.util.Cm(5.08)],
    3: [pptSubtitle, pptx.util.Pt(28), black, pptx.enum.text.MSO_ANCHOR.TOP, pptx.util.Cm(1.27), pptx.util.Cm(8.29), pptx.util.Cm(31.33), pptx.util.Cm(2.75)],
    4: [author, pptx.util.Pt(24), black, pptx.enum.text.MSO_ANCHOR.BOTTOM, pptx.util.Cm(1.27), pptx.util.Cm(11.06), pptx.util.Cm(17.59), pptx.util.Cm(2.03)],
    5: [date, pptx.util.Pt(20), black, pptx.enum.text.MSO_ANCHOR.TOP, pptx.util.Cm(1.27), pptx.util.Cm(13.12), pptx.util.Cm(17.59), pptx.util.Cm(1.1)]
  })
    
  titleFormat_df.index = ['Text', 'Font Size', 'Colour', 'Vert Anchor', 'left', 'top', 'width', 'height']
      
  for sid in titleFormat_df:
    sh = slide.shapes.add_shape(pptx.enum.shapes.MSO_SHAPE.RECTANGLE, titleFormat_df[sid]['left'], titleFormat_df[sid]['top'], titleFormat_df[sid]['width'], titleFormat_df[sid]['height'])
    sh.fill.background()
    sh.line.fill.background()
    tf = sh.text_frame
    tf.clear()
    tf.vertical_anchor = titleFormat_df[sid]['Vert Anchor']
    tf.paragraphs[0].alignment = pptx.enum.text.PP_ALIGN.LEFT
    
    run = tf.paragraphs[0].add_run()
    run.text = titleFormat_df[sid]['Text']
    run.font.name = 'Arial'
    run.font.size = titleFormat_df[sid]['Font Size']
    c = titleFormat_df[sid]['Colour']
    run.font.color.rgb = pptx.dml.color.RGBColor(c[0], c[1], c[2])
     
  prs.save('test.pptx')
  </code></pre>
  <p>How can I remove this formatting option? And how can I add when I want it that way?
  Thanks in advance!</p>
