Viewport streaming download (for terrain details, buildings, trees, etc...)

[GoogleCodeExporter]

The viewport streaming download sometimes doesn't work properlly, because as 
soon as the horizon comes up the streaming starts to work sometimes in a random 
way, that's why I think I might have the possibility to choose the viewport 
stream download by myself at my will.  For example, 
In the galery:
http://earth-api-samples.googlecode.com/svn/trunk/examples/bounds.html

this example can make you an idea of what I mean in some cases, if you get too 
close to the ground the viewport downloading stream would start to download the 
buildings from far away just because they are in the viewport sight. It could 
be very interesting if I can tell GE wich area do I want to stream 
independently of what I'm looking at.
Thanks for your atention.

This are streams of buildings, really close to the floor, sometimes I arrive 
till ground level, and as you can see the streaming bar seems to be completed 
and I guess... it is because when you force a refresh of the view, the only 
system I know at the moment is making the view look at the ski, this way the 
ViewportGlobeBounds losses the anchor with earth and it seems it restarts again 
the new viewportGlobeBound or refreshes the view (i don't know exactly what it 
does) when the view takes contact again with the horizon. Inmediatly (like if 
it is allready streamed and just comes out) the buildings get updated like this 
and everything is normal.

I've asked several coleges in this and other forums and wrote a couple of times 
regarding any help in this issue. My other programmers friends thought this was 
normal, and google earth is this way... sometimes it works and sometimes not, 
and I do believe this decline the real quality of GE.
For 11th time and supporting with some graphical examples, can I refresh the 
buildings view when I want to, without looking to the ski and turning back to 
ground the view??

If not and you know how to fix it... I would advise you to change it for the 
best of GE.
Thank you very much in advance and hopping some direct contact with google 
crew, i could explain better if neccessary.
