2006-11-09  Shiro Kawai  <shiro@acm.org>

	* INSTALL.in, doc/extract: moved from using escm to generate INSTALL
	  and INSTALL.eucjp, to avoid complication about character encodings.
	  Using 'extract' script instead.

	  sqrt for float operation.

2006-11-08  Shiro Kawai  <shiro@acm.org>

	* src/gen-ptrs.scm (main): typo fix (pointed by Erik Greenwald)

	* src/gauche-gl.c (Scm_GLGetProcAddress): try glXGetProcAddressARB
	  first, before glXGetProcAddress, since ARB version is the 'proper'
	  one.  See the comment in the source for the details.

2006-03-04  Shiro Kawai  <shiro@acm.org>

	* configure.in: drop 'powerpc' from the check of OSX, for we have
	  x86 OSX now.

2005-11-05  Shiro Kawai  <shiro@acm.org>

	* release 0.4.1

2005-08-30  Shiro Kawai  <shiro@acm.org>

2005-08-01  Shiro Kawai  <shiro@acm.org>

	* src/configure.in, Makefile.ins: adapted to the new extension
	  building scheme (requires Gauche-0.8.6).

2005-07-02  Shiro Kawai  <shiro@acm.org>

	* src/gauche-gl.c (Scm_GLGetProcAddress): typo fix (Pointed by
	  Takashi Ishizaki).

2005-06-30  Shiro Kawai  <shiro@acm.org>

	* release 0.4
	
	* src/gauche-gl.h, src/gauche-gl.c, configure.in: Make 
	  Scm_GLGetProcAddress work on MacOSX by using glutGetProcAddress
	  (Patch provided by Issac Trotts.)

2005-06-14  Shiro Kawai  <shiro@acm.org>

	* cg/*, examples/cg/* : Added NVidia's Cg Toolkit binding written
	  by Issac Trotts.
	* configure.in, Makefile.in, README, INSTALL.esc: changed
	  accordingly.

2005-06-10  Shiro Kawai  <shiro@acm.org>

	* src/gen-ptrs.scm : use different name for the function ptr
	  variables from the GL function name, to avoid possible conflict
	  with gl.h.
	  Also improved the #ifdef guards around typedefs.

	* src/glext-lib.stub : changed some APIs for consistency (e.g.
	  gl-uniform*).
	* examples/slbool/* : fixed accordingly.

	* doc/gauche-gl-ref.texi : documented most supported GL and GLU
	  APIs.

2005-06-08  Shiro Kawai  <shiro@acm.org>

	* lib/gl/simple-image.scm : added.
	* src/glext-lib.stub, src/gl-lib.stub: more API support.
	* examples/images/* : added.

2005-06-05  Shiro Kawai  <shiro@acm.org>

	* src/glext-api.scm: API definition of GL extension.  We no longer
	  rely on glext.h and generate various files from this file, since
	  we cannot count on the client's glext.h which may likely be out of
	  date and cause so much headache.
	
	* src/gen-syms.scm, src/gen-ptrs.scm : from glext-api.scm, these
	  scripts generates gl-syms.h, gl-ptrs.h and gl-syms.c, which 
	  define all GL extension enums and function pointers.

	* src/gl-syms.stub : removed, for the info is now generated
	  from glext-api.scm.

	* src/gauche-gl.c (Scm_GLGetProcAddress): wrapper of glXGetProcAddress
	  or wglGetProcAddress.

	* src/glext-lib.stub : all calls to GL extensions are now through
	  function pointers, and ENSURE macro sets the pointer by
	  Scm_GLGetProcAddress.

	* src/gauche-gl.h, src/gauche-gl.c, src/gl-lib.stub, lib/gl.scm:
	  Added <gl-boolean-vector> type to represent GLboolean[].
	  Changed gl-get-boolean(!) to deal with <gl-boolean-vector>
	  rather than <u8vector>.  THIS IS AN INCOMPATIBLE CHANGE.
	  Note that a single value return of gl-get-boolean also changed
	  to return a boolean value rather than an integer.
	* doc/gauche-gl-ref.texi: adding more stuff.

2005-06-04  Shiro Kawai  <shiro@acm.org>

	* lib/gl.scm : added gl-extension-supported?, gl-version<?, etc.

	* src/glext-lib.stub : added more bindings on vertex attributes.

2005-06-01  Shiro Kawai  <shiro@acm.org>

	* examples/slbook : added OpenGL shading language book examples.
	
	* src/gauche-gl.h : define GL_GLEXT_PROTOTYPES to include gl
	  extension procedure declarations properly.  (In futuer, we should
	  use function-pointer-finding way instead of relying on compile-time
	  availability of extensions).
	* src/gauche-gl.c (Scm_GLGetProcAddress): added #ifdefs to compile
	  properly.

	* src/glext-lib.stub : more bindings (patch provided by Issac Trotts).

2005-05-30  Shiro Kawai  <shiro@acm.org>

	* src/glu-lib.stub (glu-build-2D-mipmaps): added (provided by
	  Issac Trotts)

2004-08-21  Shiro Kawai  <shiro@acm.org>

	* lib/gl/util.scm : added
	* src/glext-lib.stub : added ARB extension bindings.

	  glext-lib.stub
	* src/Makefile.in : added glext-lib.stub

2004-07-05  Shiro Kawai  <shiro@acm.org>

	* */Makefile.in : added $(DESTDIR) to install target directories

2003-03-07  Shiro Kawai  <shiro@acm.org>

	* doc/extract (filter): escaped '{' and '}' in regexp.

2003-02-10  Shiro Kawai  <shiro@acm.org>

	* release 0.2.2
	* doc/extract : use the newest extract so that the monolingual docs
	  can be genarated by gosh with any internal encodings.

2003-02-07  Shiro Kawai  <shiro@acm.org>

	* src/gauche-math3d.c (Scm_TRSToMatrix4fv): The order of
	  multiplication was wrong (was TSR, not TRS).  So as in
	  Scm_TQSToMatrix4fv.

2003-01-29  Shiro Kawai  <shiro@acm.org>

	* release 0.2.1
	* configure.in : add -lX11 -lXext to link gauche-gl if we're
	  on X11 systems.  FreeBSD seems to need it, and it won't do
	  harm as far as we're on X11.
	* src/gauche-gl.c : add brackets around GLU object classes
	  for consistency.
	* src/Makefile.in : install math3d.h under gauche subdirectory.
