  39. <h2>New Features</h2>
  40. <ul>
  41. <li>OpenGL Shading language support
  42. <br>
  43.    This includes the GL_ARB_shader_objects, GL_ARB_shading_language_100,
  44.    GL_ARB_vertex_shader and GL_ARB_fragment_shader extensions.  Most of
  45.    the work was done by Michal Krol.
  46.    There's probably a fair number of bugs since this is a pretty large,
  47.   complicated body of code.
  48. <br>
  49.   The OpenGL 2.0 interface to these features will be implemented in a
  50.   future version of Mesa,
  51.  
  52. <li>GL_EXT_timer_query
  53. <br>
  54.   Used to measure the time of OpenGL operations at high precision.
  55.   Only supported in the software/Xlib driver at this time.
  56.  
  57. <li>GL_EXT_packed_depth_stencil
  58. <br>
  59.   Defines a new GL_DEPTH_STENCIL_EXT pixel format.
  60.  
  61. <li>GL_EXT_framebuffer_blit
  62. <br>
  63.   A simplified glCopyPixels-like feature for copying pixel rectangles.
  64.  
  65. <li>GL_ARB_half_float_pixel
  66. <br>
  67.   Adds a new half-precision floating point format for image transfers,
  68.   such as for glDrawPixels, glReadPixels, glTexImage, etc.
  69. </ul>
  70.  
  71. <h2>Changes</h2>
  72. <ul>
  73. <li>removed GL_HP_occlusion_test (use GL_ARB_occlusion_query instead)
  74. <li>removed GL_SGIX/SGIS_pixel_texture extensions
  75. </ul>
  76. <h2>Bug fixes</h2>
  77. <ul>
  78. <li>fixed glxcontextmodes.c datatype problem (bug 5835)
  79. <li>fixed aix-gcc build/install bugs (bug 5874)
  80. <li>fixed some bugs in texture env program generation
  81. <li>glXCopyContext() didn't handle texture object bindings properly
  82. <li>glXCopyContext() didn't copy all lighting state
  83. <li>fixed FreeBSD config (Pedro Giffuni)
  84. <li>fixed some minor framebuffer object bugs
  85. <li>replaced dprintf() with _glu_printf() in GLU (bug 6244)
  86. <li>fixed a number of thread safety bugs/regressions
  87. <li>fixed a number of GLU tesselator bugs (John Shell, bug 6339)
  88. <li>paletted texturing was broken w/ floating point palettes (K. Schultz)
  89. <li>lots of assorted framebuffer object bug fixes
  90. </ul>
  91.  
  92.  
  93. <h2>Known Issues</h2>
  94. <ul>
  95. <li>Rendering to depth textures will not work.  Rendering to GL_DEPTH_STENCIL
  96. textures should work.
  97. </ul>
  98.  
  99.  
  100. <h2>Driver Interface Changes</h2>
  101. <ul>
  102. <li>Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by
  103. the two-sided versions: Driver.Stencil*Separate().
  104. <li>Render-to-texture: The functions for rendering to textures have changed.
  105. </ul>
  106.  
  107.  
  108. <h2>To Do (someday) items</h2>
  109. <ul>
  110. <li>Switch to freeglut
  111. <li>Increase MAX_DRAWBUFFERS
  112. <li>Fix linux-glide target/driver.
  113. <li>Fix lambda calculation for frag progs.
  114. </ul>
  115.
