Creates a high-level SubTexture representing a sub-region of any other Texture.
The sub-region must strictly lye within the bounds of the parent_texture. The returned texture implements the
MetaTexture interface because it's not a low level texture that hardware can understand
natively.
<note>Remember: Unless you are using high level drawing APIs such as cogl_rectangle or other APIs documented to
understand the MetaTexture interface then you need to use the
MetaTexture interface to resolve a
SubTexture into a low-level texture before drawing.</note>
