Hi, I have a similar case in perspective mode:
I use a fixed world, my viewing platform is moved in the VWord
and my texts are attached to billboards.
I still have to resize text as you already do but that's not to bad, i have
had to tweak the billboards a bit for them to work correctly but I can help
you there if need be

>for each of these points, we also have a text string that is associated
with it
