  10 Introduction
  11 ------------
  12
  13 Mesa uses an even/odd version number scheme like the Linux kernel.
  14 Even numbered versions (such as 4.0) designate stable releases.
  15 Odd numbered versions (such as 4.1) designate new developmental releases.

  18 New Features in Mesa 4.1
  19 ------------------------
  20
  21 New extensions.  Docs at http://oss.sgi.com/projects/ogl-sample/registry/
  22
  23 GL_NV_vertex_program
  24
  25     NVIDIA's vertex programming extension
  26
  27 GL_NV_vertex_program1_1
  28
  29     A few features built on top of GL_NV_vertex_program
  30
  31 GL_ARB_window_pos
  32
  33     This is the ARB-approved version of GL_MESA_window_pos
  34
  35 GL_ARB_depth_texture
  36
  37     This is the ARB-approved version of GL_SGIX_depth_texture.
  38     It allows depth (Z buffer) data to be stored in textures.
  39     This is used by GL_ARB_shadow
  40
  41 GL_ARB_shadow
  42
  43     Shadow mapping with depth textures.
  44     This is the ARB-approved version of GL_SGIX_shadow.
  45
  46 GL_ARB_shadow_ambient
  47
  48     Allows one to specify the luminance of shadowed pixels.
  49     This is the ARB-approved version of GL_SGIX_shadow_ambient.
  50
  51 GL_EXT_shadow_funcs
  52
  53     Extends the set of GL_ARB_shadow texture comparision functions to
  54     include all eight of standard OpenGL dept-test functions.
  55
  56 GL_ARB_point_parameters
  57
  58     This is basically the same as GL_EXT_point_parameters.
  59
  60 GL_NV_point_sprite
  61
  62     For rendering points as textured quads.  Useful for particle effects.

  65 Device Driver Status
  66 --------------------
  67
  68 A number of Mesa's software drivers haven't been actively maintained for
  69 some time.  We rely on volunteers to maintain many of these drivers.
  70 Here's the current status of all included drivers:
  71
  72
  73 Driver                  Status
  74 ----------------------  ---------------------
  75 XMesa (Xlib)            implements OpenGL 1.3
  76 OSMesa (off-screen)     implements OpenGL 1.3
  77 FX (3dfx Voodoo1/2)     implements OpenGL 1.3
  78 SVGA                    implements OpenGL 1.3
  79 Wind River UGL          implements OpenGL 1.3
  80 Windows/Win32           implements OpenGL 1.3
  81 DOS/DJGPP               implements OpenGL 1.3
  82 GGI                     needs updating
  83 BeOS                    needs updating
  84 Allegro                 needs updating
  85 D3D                     needs updating
  86 DOS                     needs updating

  91 XXX Things To Do Yet XXXX
  92 -------------------------
  93
  94 Verify x86 code for normal transformation works with new 4-element normal
  95 vector arrays.  Pretty sure the SSE code is wrong.
  96
  97 Finish up NV_vertex_program support for evaluators.  Vertex arrays seem
  98 to work as of 4/21/2002.
  99
 100 Move sw_span struct into swrast context instead of allocating it on
 101 the stack.  Allow multiple points to be rendered into one sw_span.
 102
 103 Investigate the normal transformation bug when using non-uniform
 104 scale matrices.
 105
 106 _tnl_end() has flushing forced on.
 107
 108 improve point/line rendering speed.
 109
 110 readpixels from stencil/z should respect ctx->ReadBuffer
 111
 112 glVertexAttrib*NV(index>15) should cause an error.
 113
 114 GL_ARB_texture_env_crossbar: Allows any texture combine stage to reference
 115 any texture source unit
