* add static cleanup handlers to GLTexturePrivate and GLRenderTarget
* revert the runtime resolved features (e.g. RenderTargets are not
supported once we run the cleanup code)
* clear the extension lists
* reset the version variables

also work around broken fbo texture clearing on fglrx
so far supports FBO/glClear and resorts to glTexSubImage2D
if the fbo cannot be created or is (in case of fglrx)
known to break, resort to glTexImage2D loading of an
argb array of zeros

This method returns a matrix that transforms normalized or un-normalized
texture coordinates, taking the texture target and y-inversion flag into
account.
This patch changes the behavior of strictly bound textures such that
they are only updated if the corresponding window has been damaged.
Additionally GLTexture now keeps track of the current filter and
wrapmode setting.

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
