Update paged geometry to latest version

[GoogleCodeExporter]

Paged geometry should be updated to the latest svn version to get some 
performance improvement.

We have made some changes in paged-geom so this should be the process of 
updating it to latest version:

1. get paged geometry version 1.1.0 (exactly this version, since this is the 
one we used)
2. generate a diff against the paged-geom in our source tree to have a list of 
the changes we made
3. now hand-merge the diff into the newest (svn) paged-geom - where possible, 
it is best to avoid changing the paged geom source. for example, the cache 
directory for it can also be set with PagedGeometry::setCacheDir instead of 
changing it in the source.

I've started this now in a seperate branch. Issues left:

1. impostors are looking all wrong (objects have wrong scale, distance to 
camera, etc)
2. Grass wave, fade
3. Trees wave
