	* version 1.03.
	* Fixed the pfm reader to treat rows as ordered from bottom to top.
	* Added support for xz compression.
2006-10-07    <nakamaru@gmail.com>
	* version 1.02.
	* Modified texture images to have edge-margins for avoiding
	  GL_CLAMP issues, while not using GL_CLAMP_TO_EDGE (so the

	  glutFullScreen() on MacOSX.
	* Added MacOSX as a target.
	* Modified reshape() not to align width/height to even numbers.
