[osg-users] OpenSceneGraph-3.6.1 release candidate 3 tagged

[Robert Osfield]

Hi Dan,

I have had another look at this bug and using your text example I do
see some odd behaviour so I've rewritten TextBase::computeMatrix() so
use higher level matrix maths that is easier to understand than the
"fast" maths version that unrolled all the the matrix ops but was very
hard to follow.  Hard to follow -> Hard to debug...

The new version of the scale maths now works better on your two text
test programs, and osgtext looks to behaving itself too.

    https://github.com/openscenegraph/OpenSceneGraph/commit/362e355db28582c839c88ddd6ede1d1ae1d74237

Now that this is fixed I will create another 3.6.1-rc, hopefully this
next one will be the last and we can finally get 3.6.1 out the door.

Robert.
