Copied the meshcam scene files into an alternate location and started 
going through the baking demo ....

There were some warnings associated with not setting assumed_gamma 
before calling/using rgb vectors, and warnings in light_source 
definitions ... suspicious value after rgb. I fixed all those, and 
submitted changes to revision control, but that didn't address the 
unexpected results I'm seeing!!!

Has anyone else worked through the demo?

Just tried it on Windows version. It works fine.

   Hmmm... everything seems to work fine here, both the bakind and the
rendering steps (using final 3.7 compiled from sources a few months
ago). BTW, it renders fine with Uberpov too...

Thanks for the nudge ... I've been using uberpov-dev for a bit and that 
works fine. Since povray is obviously busted on my system, I did a fresh 
build from the perforce repository and that appears to be broken. Can 
anyone with perforce access confirm? I did a fresh pull/build from the 
povray github and that works fine. The plot thickens!

Rebuilding (after getting latest revision of smp at 6194) (only make
clean, ./configure & make, not running prebuild.sh ) : compile & link
fine with:

./configure COMPILED_BY="Jérôme Grimbert <jgr### [at] freefr>"
--disable-io-restrictions LIBS="-lboost_system -lboost_thread"

BUT
./configure COMPILED_BY="Jérôme Grimbert <jgr### [at] freefr>"
--disable-io-restrictions LIBS="-lboost_system"

succeeds with configure, yet the final link fails.

and so on (many pages). (sorry, compiler message is in French)

Test done on Ubuntu 13.10, 64 bits (x86_64)

it's compiles and links just fine on older 32bit system ... I /just/ 
pass the COMPILED_BY string, but it produces the odd image posted 
earlier. I haven't tried running some of my old scenes just to see. I 
got rid of the perforce version in favor of github. I'm wondering if it 
has anything to do with /all/ the re-factoring work that's been done.

   Hmmm... this exact problem seems to be happening on the latest master 
branch from github (works fine on the stable branch). Seems like 
something went wrong with the mesh camera...

As it turns out, James was onto something back then already: The POV-Ray 
master branch was still ok then, but he must have built from the 
refactor branch, where the bug had been introduced on 2013-12-16 with 
commit 5cee76e.

That branch was merged into the POV-Ray master branch on 2014-06-13 
(which happens to have been a Friday, yes) with commit 2c4e9f2.

Quite a silly bug actually, and a one-liner to fix.

   I didn't use the mesh cam for a while, but some weeks ago someone was 
toying with my lightmapping demo, and got very strange results. I tried 
it myself, and the result looked familiar... thanks for the fix!
