Indeed...

I think this is realistic...
After all, the glow would not be like glowing air, but more like
lens-flare.  If the mirror reflects an object that is that bright you
can see a glow, and the reflection covers the entire mirror, the
mirror should glow too, I think.

Yes, but I think post-process-glows would only be useful to create
lensflarish glows.  Which, I think, is good.

I tried.
I don't know how to do that with Borland C++
I get lots of different windows...
When I start a new project, I get:
-+  proj0000.exe [.exe]
 |
 + proj0000.cpp [.cpp]
 |
 + proj0000.def [.def]
 |
 + proj00000.rc [.rc]

Where should I put the code?
