I tried to sponsor your patch to raring, but libreoffice fails to build
in my amd64 pbuilder instance:

FAILURES!!!
Tests run: 1,  Failures: 1

see full error log at /tmp/buildd/libreoffice-3.6.2~rc2/workdir/unxlngx6.pro/JunitTest/toolkit_unoapi/done.log
to rerun just this failed test without all others, run:

    make
/tmp/buildd/libreoffice-3.6.2~rc2/workdir/unxlngx6.pro/JunitTest/toolkit_unoapi/done

cd into the module dir to run the tests faster
Or to do interactive debugging, run two shells with (Linux only):

    make debugrun
    make gb_JunitTest_DEBUGRUN=T /tmp/buildd/libreoffice-3.6.2~rc2/workdir/unxlngx6.pro/JunitTest/toolkit_unoapi/done

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.
      See. https://launchpadlibrarian.net/49398355/Screenshot-OpenOffice.org%203.0-PresentationMode.png

  [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.

  Binary package hint: openoffice.org
  Binary package hint: libreoffice

  1) lsb_release -rd
  Description:	Ubuntu 12.10
  Release:	12.10

  
  2)  apt-cache policy libreoffice-impress
  libreoffice-impress:
    Installed: 1:3.6.2~rc2-0ubuntu4
    Candidate: 1:3.6.2~rc2-0ubuntu4
    Version table:
   *** 1:3.6.2~rc2-0ubuntu4 0
          900 http://archive.ubuntu.com/ubuntu/ quantal-updates/main i386 Packages
          400 http://archive.ubuntu.com/ubuntu/ quantal-proposed/main i386 Packages

       1:3.6.2~rc2-0ubuntu3 0
          500 http://archive.ubuntu.com/ubuntu/ quantal/main i386 Packages

  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 TECHNICN.TTF /usr/share/fonts
  && sudo fc-cache -f -v && loimpress -nologo
  ~/Desktop/BoldTechnicalFontTest/Desktop/BoldTechnicalFontTest.odp

  Click F5 the font is not fuzzy.

  4) What happened instead is the font is fuzzy.

  First reproduced in LO Maverick 1:3.3.1-1ubuntu3~maverick1, and
  reproduced in Natty.

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