title: Bind GLES texture to GL_TEXTURE_2D from GL_TEXTURE_EXTERNAL_OES
body: <p>I have a texture, bound to GL_TEXTURE_EXTERNAL_OES target</p>
  
  <pre><code>    GLES20.glBindTexture(GLES11Ext.GL_TEXTURE_EXTERNAL_OES, textures[0]);
      GLES20.glTexParameteri(GLES11Ext.GL_TEXTURE_EXTERNAL_OES, GLES20.GL_TEXTURE_WRAP_S, GLES20.GL_CLAMP_TO_EDGE);
      GLES20.glTexParameteri(GLES11Ext.GL_TEXTURE_EXTERNAL_OES, GLES20.GL_TEXTURE_WRAP_T, GLES20.GL_CLAMP_TO_EDGE);
      GLES20.glTexParameteri(GLES11Ext.GL_TEXTURE_EXTERNAL_OES, GLES20.GL_TEXTURE_MIN_FILTER, GLES20.GL_NEAREST);
      GLES20.glTexParameteri(GLES11Ext.GL_TEXTURE_EXTERNAL_OES, GLES20.GL_TEXTURE_MAG_FILTER, GLES20.GL_NEAREST);
  </code></pre>
  
  <p>How can rebind it to GL_TEXTURE_2D target? 
  <code>GLES20.glBindTexture(GLES20.GL_TEXTURE_2D, textures[0]);</code> provides error</p>
