Robert Osfield 67202b2662 From Romain Ouabdelkader, "This is a fix for osgText to calculate kerning and to load glyph3D with the text's font resolution.
Font::getKerning(...), Font::getGlyph3D(...) doesn't ask for a font resolution so it uses the last font resolution requested by Font:: getGlyph(...).
This can leads to different results depending of the precedent call to Font::getGlyph(...).
See http://lists.openscenegraph.org/pipermail/osg-users-openscenegraph.org/2016-January/271952.html for more infos.

This fix adds a font resolution parameter to Font::getKerning(...), Font::getGlyph3D(...) and to the font implementations.
This was made under the base revision r15182."
