[mohij <patrick@xxxxxxxxx>]

mohij has proposed merging lp:~patrick-zakweb/openlp/bug-936281 into lp:openlp.

Requested reviews:
  Raoul Snyman (raoul-snyman)

For more details, see:
https://code.launchpad.net/~patrick-zakweb/openlp/bug-936281/+merge/133998

- Made fix configurable in advanced menu.
- Corrected " -> '
- Removed check for similarity of colors since it makes no sense when the option is configurable.
- Fixed a bug related to mix up of color systems.

Example screenshots:

ftp://ftp.gmerlin.de/pub/upload/with_fix_win.png

On linux there is barely a difference noticeable, on windows the difference is obvious.

This partially fixes bug #936281.
Tested on Kubuntu 12.04 and Windows XP SP3.
