Hi Brendan,

Thank you for the patch. I have to admit that I did not find time to look in 
the details of the code. I compiled the changes on my computer and the 
rendering time increased by a factor of 20 or more. Is this only the case on 
my computer? I'm using qt 4.2.3 on ubuntu 6.10. Should I try it with qt4.3

It is important for my university project, a mapserver with qgis, that third 
party apps can use the qgis libs without a running X server. So my question 
is if this would still be possible with the proposed changes.
