Philipp Knechtges 4f50a8df3c kwin: Implement "use by value" and implicit sharing for GLTexture.
Additionally:
- hide the GLTexture implementation using dpointers
- drop the unused function SceneOpenGL::Texture::optimizeBindDamage()
- Texture::load now loads a new texture and does not update the existing one
