Instead of directly manipulating GL textures itself, CoglTexture2DSliced now works in terms of CoglHandles. It creates the texture slices using cogl_texture_new_with_size which should always end up creating a CoglTexture2D because the size should fit. This allows us to avoid replicating some code such as the first pixel mipmap tracking and it better enforces the separation that each texture backend is the only place that contains code dealing with each texture target.
