glIsTexture returns GL_TRUE if texture is currently the name of a texture. If texture is zero, or is a
       non-zero value that is not currently the name of a texture, or if an error occurs, glIsTexture returns
       GL_FALSE.

       A name returned by glGenTextures(), but not yet associated with a texture by calling glBindTexture(), is
       not the name of a texture.
