    now be much more portable
  - removed deprecated OSX font setting calls
  - texture properties are now returned by material3d()
  - allowed normals and texture coordinates to be specified in triangles, quads and surfaces
  - normals may be specified in qmesh objects, but (at present) subdivide removes them
  - material3d() now preserves the values of unspecified parameters (as documented,
    but not previously functioning)
  - clear3d() can now reset material properties to the defaults, and
    open3d() does this.
  - minor fix for gcc 4.3 compatibility
  - minor fix for R 2.5+ compatibility
  - allowed more general surfaces to be plotted by rgl.surface, surface3d and 
    persp3d, by specifying matrices for x and y coordinates

 v0.77
  - par3d("windowRect") returned garbage if there was no window open.
  - persp3d() and plot3d() sometimes miscalculated ranges involving NAs.
  - select3d() and rgl.select() produced a very inefficient test function.
  
 v0.78
  - fix miscalculation of mouseMatrix that caused disappearing views.
  - rgl.texts() and text3d() can now handle font and size specifications
    using the FreeType library on any platform, or GDI on Windows. 
  - adj is supported both horizontally and vertically in drawing text.
  - rgl.pop was very slow when given a long list of ids.
  - a workaround for OSX 10.5 OpenGL problems has been incorporated
    (thanks to mkv22@cam.ac.uk).

v0.79
  - rgl.pop() could cause corruption when multiple windows were open.
  - added mouseCallbacks demo, to show R implementations of standard
    mouse handlers, multiple connected windows, stereo view, etc.

    time.
  - fixed configuration problems in OS X

v0.82
  - rewrote internal rendering of transparent and anti-aliased shapes,
    so they will be rendered better when there are several in the same 
    scene
  - added material properties "point_antialias", which causes points to be 
    drawn as smooth circles, and "line_antialias", which causes
    lines to be antialiased.
  - fixed a bug in the bounding box decoration which caused axis labels
    to be plotted in the wrong place.
  - fixed a bug in the Windows driver which caused the standard system 
    font to disappear when justified.
  - added material parameter lwd for line width; size now applies only
    to points.
  - increased default point size to 3 pixels across.
  - fixed bug in open3d:  "..." was being ignored.
  - fixed bug in qmesh3d:  homogeneous=FALSE coordinates were not
    handled properly.
  - movie3d gains a "type" argument to set the output type, and the 
    "convert" argument is more flexible.
  - rgl.snapshot() gives more informative error messages when libpng is
    not available.
  - axis3d() now uses format() rather than as.character() to give
    nicer looking labels.
  - the clipping volume calculation was incorrect when scaling was used.
  - use R warning() to report messages, rather than popups or REprintf.

    to illustrate its use.

    Brian Ripley).
  - Fixed rgl.pixels example for weird displays.
  - Did not assume OpenGL 1.2 was available in material properties.

  - Fixed demo(stereo) to add sync in X11:  X windows seemed to grab
    images before they were redrawn.
  - Rearranged headers for Win64 compatibility (contributed by Alex 
    Chen).
    
v0.83-3
  - Quick fix for R 2.9.x compatibility, and to remove accidental change
    introduced in v0.83 which caused errors on plotting without open3d().

v0.84
  - Added triangle meshes, shape lists, the Platonic solids and a cuboctahedron.
  - Added classes mesh3d and shapelist3d; qmesh3d is only kept for 
    back compatibility. 
  - Bug fix to stop crashes when material is set before the first window is
    opened.
    
v0.85

  - Fixed configure.ac as suggested by Jens Elkner.
  - Updated declarations for libpng 1.4.0 compatibility.
  - An off-by-one error caused the "alpha" component of the material
    properties to be messed up. (Bug #809)

    (Reported by Michael Friendly.)

    set HAVE_PNG to a non-empty value, and rgl will look for 
    the libpng files in the default LOCAL_SOFT location when installing.
  - Added depth_mask and depth_test material properties, to allow control
    over how objects are obscured by each other.
