[Tim Bentley <856296@xxxxxxxxxxxxxxxxxx>]

This code is not added for OpenLP but for Powerpoint etc to allow Powerpoint to render a screen and then the preview to be updated.
This will be relevant to all items with this capability ItemCapabilities.ProvidesOwnDisplay  so needs to be handled with care.

For Songs , Images etc there is a loop in the maindisplay code which
waits for QWebKit to say it has finished painting the screen. This is a
QT triggered event with a 0.1 sec timer to allow the machine to not get
loop tied up.

Title:
  Improve performance of song loading for Preview/Live

Status in OpenLP - Worship Presentation Software:
  New

Bug description:
  I think we should try to optimize song loading for Preview/Live
  because users will often double click on a song in song list and want
  to see the preview of the song.
