PARAMETERS
       texture  Specifies a value that may be the name of a texture.

DESCRIPTION
       glIsTexture  returns  GL_TRUE if texture is currently the name of a tex‐
       ture.  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.

NOTES
       glIsTexture is available only if the GL version is 1.1 or greater.

ERRORS
       GL_INVALID_OPERATION is generated if glIsTexture is executed between the
       execution of glBegin and the corresponding execution of glEnd.
