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Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by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