(Please take C++11 discussion to another thread.)
If no one is setting OSG_USE_REF_PTR_IMPLICIT_OUTPUT_CONVERSION to OFF, I'll
submit a change that removes the variable (with the code behaving as if the
variable were present and set to ON).
Here's some history on the ref_ptr issue:
* In OSG 2.6.x and earlier, you always had to use ref_ptr::get() to access the
pointer address. (This is the same behavior you'd get today if you set
OSG_USE_REF_PTR_IMPLICIT_OUTPUT_CONVERSION to the OFF value.)
* Sometime in the 2.7 dev series, OSG_USE_REF_PTR_IMPLICIT_OUTPUT_CONVERSION was
added with the default ON value, but there was consensus in osg-users at that
time that OSG itself should build with the variable set either way.
* OSG 2.8.0 was the first stable release with
OSG_USE_REF_PTR_IMPLICIT_OUTPUT_CONVERSION (set to ON by default).
