Bug description:
  
  [Impact]
   * bold characters blurs horizontally if the font does not have a bold typeface. This makes characters less readable.
     See. https://launchpadlibrarian.net/49398403/Screenshot-OpenOffice.org%203.2-PresentationModeFuzzyFont.png
   * There is a workaround, which is turning off hardware acceleration. But it makes animations and transitions quite slow.

  
  [Test Case]

   1. type some text and make it as bold in Impress editing mode.
   2. apply font which does not have a bold typeface to the text.
      e.g. "Takao PGothic" font in fonts-takao-pgothic package.
   3. press F5(presentation)
   4. the text blurs horizontally. And the look of the font differs from editing mode.
      See. https://launchpadlibrarian.net/49398403/Screenshot-OpenOffice.org%203.2-PresentationModeFuzzyFont.png
   5. update to -proposed package
   6. the text does not blurs horizontally. And the look of the font is nearly the same as editing mode.

  [Regression Potential]

  low.
  The rendering way of this part was far from good. This fix is not a perfect solution, but it will improve it.

  3) What is expected to happen is when one opens the following at the
  Terminal:

  cd ~/Desktop && wget
  https://bugs.launchpad.net/ubuntu/+source/openoffice.org/+bug/585910/+attachment/1405216/+files/BoldTechnicalFontTest.zip
  && file-roller -h BoldTechnicalFontTest.zip && cd
  BoldTechnicalFontTest/.fonts && sudo mv TECHNICI.TTF /usr/share/fonts
  && sudo mv TECHNICN.TTF /usr/share/fonts && sudo fc-cache -f -v &&
  sudo reboot

  Upon restart at the Terminal:

  loimpress -nologo
  ~/Desktop/BoldTechnicalFontTest/Desktop/BoldTechnicalFontTest.odp

  Click F5 the font is not fuzzy.

  4) What happened instead is the font is fuzzy.

  WORKAROUND: click Tools -> Options -> LibreOffice -> View -> uncheck
  Use hardware acceleration checkbox -> OK button -> F5
