Preserves a [ texture-unit, texture-target ] state.

The states keys are the retrieved active texture-unit and the given texture-target for which the following states are being queried: 

  - texture-object
  - GL.GL_TEXTURE_MAG_FILTER
  - GL.GL_TEXTURE_MIN_FILTER
  - GL.GL_TEXTURE_WRAP_S
  - GL.GL_TEXTURE_WRAP_T
