	/**
	 * Creates one of the following:
	 * 
	 * 

	 * 
an OpenCL 2D image object from an OpenGL 2D texture object or a single face of an OpenGL cubemap texture object,
	 * 
an OpenCL 2D image array object from an OpenGL 2D texture array object,
	 * 
an OpenCL 1D image object from an OpenGL 1D texture object,
	 * 
an OpenCL 1D image buffer object from an OpenGL texture buffer object,
	 * 
an OpenCL 1D image array object from an OpenGL 1D texture array object,
	 * 
an OpenCL 3D image object from an OpenGL 3D texture object.
	 * 
	 * 
	 * 
If the state of a GL texture object is modified through the GL API (e.g. {@link GL11#glTexImage2D}, {@link GL12#glTexImage3D} or the values of the
	 * texture parameters {@link GL12#GL_TEXTURE_BASE_LEVEL} or {@link GL12#GL_TEXTURE_MAX_LEVEL} are modified) while there exists a corresponding CL image
	 * object, subsequent use of the CL image object will result in undefined behavior.
	 * 
	 * 
The {@link CL10#clRetainMemObject RetainMemObject} and {@link CL10#clReleaseMemObject ReleaseMemObject} functions can be used to retain and release the image objects.
	 *
	 * @param context        a valid OpenCL context created from an OpenGL context
	 * @param flags          a bit-field that is used to specify usage information. One of:
{@link CL10#CL_MEM_READ_ONLY MEM_READ_ONLY}
{@link CL10#CL_MEM_WRITE_ONLY MEM_WRITE_ONLY}
{@link CL10#CL_MEM_READ_WRITE MEM_READ_WRITE}
	 * @param texture_target defines the image type of {@code texture}. No reference to a bound GL texture object is made or implied by this parameter. One of:
{@link GL11#GL_TEXTURE_1D}
{@link GL30#GL_TEXTURE_1D_ARRAY}
{@link GL31#GL_TEXTURE_BUFFER}
{@link GL11#GL_TEXTURE_2D}
{@link GL30#GL_TEXTURE_2D_ARRAY}
{@link GL12#GL_TEXTURE_3D}
{@link GL13#GL_TEXTURE_CUBE_MAP_POSITIVE_X}
{@link GL13#GL_TEXTURE_CUBE_MAP_POSITIVE_Y}
{@link GL13#GL_TEXTURE_CUBE_MAP_POSITIVE_Z}
{@link GL13#GL_TEXTURE_CUBE_MAP_NEGATIVE_X}
{@link GL13#GL_TEXTURE_CUBE_MAP_NEGATIVE_Y}
{@link GL13#GL_TEXTURE_CUBE_MAP_NEGATIVE_Z}
{@link GL31#GL_TEXTURE_RECTANGLE}
	 * @param miplevel       the mipmap level to be used. Implementations may return {@link CL10#CL_INVALID_OPERATION INVALID_OPERATION} for {@code miplevel} values > 0. If
	 *                       {@code texture_target} is {@link GL31#GL_TEXTURE_BUFFER}, {@code miplevel} must be 0.
	 * @param texture        the name of a GL 1D, 2D, 3D, 1D array, 2D array, cubemap, rectangle or buffer texture object. The texture object must be a complete texture as per
	 *                       OpenGL rules on texture completeness. The texture format and dimensions defined by OpenGL for the specified {@code miplevel} of the texture will be
	 *                       used to create the OpenCL image memory object. Only GL texture objects with an internal format that maps to appropriate OpenCL image channel order
	 *                       and data type may be used to create the OpenCL image memory object.
	 * @param errcode_ret    will return an appropriate error code. If {@code errcode_ret} is {@code NULL}, no error code is returned.
	 *
	 * @return a valid non-zero OpenCL image object and {@code errcode_ret} is set to {@link CL10#CL_SUCCESS SUCCESS} if the image object is created successfully. Otherwise, it returns a {@code NULL}
	 *         value with one of the following error values returned in {@code errcode_ret}:
	 *         
	 *         

	 *         
{@link CL10#CL_INVALID_CONTEXT INVALID_CONTEXT} if {@code context} is not a valid context or was not created from a GL context.
	 *         
{@link CL10#CL_INVALID_VALUE INVALID_VALUE} if values specified in {@code flags} are not valid or if value specified in {@code texture_target} is not one of the
	 *         values specified in the description of {@code texture_target}.
	 *         
{@link CL10GL#CL_INVALID_MIP_LEVEL INVALID_MIP_LEVEL} if {@code miplevel} is less than the value of {@code level}base (for OpenGL implementations) or zero (for
	 *         OpenGL ES implementations); or greater than the value of {@code q} (for both OpenGL and OpenGL ES).
	 *         
{@link CL10GL#CL_INVALID_MIP_LEVEL INVALID_MIP_LEVEL} if {@code miplevel} is greather than zero and the OpenGL implementation does not support creating from non-zero mipmap
	 *         levels.
	 *         
{@link CL10GL#CL_INVALID_GL_OBJECT INVALID_GL_OBJECT} if {@code texture} is not a GL texture object whose type matches {@code texture_target}, if the specified {@code miplevel}
	 *         of texture is not defined, or if the width or height of the specified {@code miplevel} is zero.
	 *         
{@link CL10#CL_INVALID_IMAGE_FORMAT_DESCRIPTOR INVALID_IMAGE_FORMAT_DESCRIPTOR} if the OpenGL texture internal format does not map to a supported OpenCL image format.
	 *         
{@link CL10#CL_INVALID_OPERATION INVALID_OPERATION} if {@code texture} is a GL texture object created with a border width value greater than zero.
	 *         
{@link CL10#CL_OUT_OF_RESOURCES OUT_OF_RESOURCES} if there is a failure to allocate resources required by the OpenCL implementation on the device.
	 *         
{@link CL10#CL_OUT_OF_HOST_MEMORY OUT_OF_HOST_MEMORY} if there is a failure to allocate resources required by the OpenCL implementation on the host.
