Added support for automatic scaling of text to screen coords. Optimized

the text implementation to provide better speed, especially by using the
alignement to screen option.

Deprecated the Text::setFontSize(,) method, which is now being replaced
by setFontResolution(,)

Fixed typos in Texture*.cpp.

Removed old deprecated methods from osg headers.
