specifically, he tried to do:
Eigen::Transform3f t = Eigen::Translation3f(1.0f, 2.0f, 0.0f);
and that failed to compile because gcc wanted to use a conversion
constructor here.
Instead with current Eigen he has to do
Eigen::Transform3f t;
t = Eigen::Translation3f(1.0f, 2.0f, 0.0f);
I'd fix it myself but I want to make sure it's not conflicting with
another design aspect...
Cheers,
Benoit
