I also struggled with this issue once and I believe osgspotlight suffers
from exactly the same "quadrant defect" if you look closely.
Would be really nice if somebody submitted a fix.

Hi Chris,
Thanks! I found that one too but it still doesn't help me figure
out how to fix the coordinates so that my projected texture renders
in the center of the projection frustum instead of the upper right
quadrant. It's strange and I can't figure it out.

Looks like the other example I have is FFP not GLSL. Here's a
working GLSL
implementation (not OSG) that should be relatively easy to feed with
OSG uniforms and such:
