HUD elements still affected by the zoom factor of the camera

[GoogleCodeExporter]

The problem can be reproduced in the following way:
1. Create a ZoomCamera
2. Create a scene
3. Change the zoom factor to 0.5
4. Create a sprite and add it to the scene

Result: The sprite will be scaled to half of the expected size.

I am using a build that was compiled on November 10, 2010, developing on Ubuntu 
10.04 x64.
