  21 New Features
  22 ------------
  23
  24 -  OpenGL Shading language support
  25
  26    This includes the GL_ARB_shader_objects, GL_ARB_shading_language_100,
  27    GL_ARB_vertex_shader and GL_ARB_fragment_shader extensions. Most of
  28    the work was done by Michal Krol. There's probably a fair number of
  29    bugs since this is a pretty large, complicated body of code.
  30
  31    The OpenGL 2.0 interface to these features will be implemented in a
  32    future version of Mesa,
  33
  34 -  GL_EXT_timer_query
  35
  36    Used to measure the time of OpenGL operations at high precision. Only
  37    supported in the software/Xlib driver at this time.
  38
  39 -  GL_EXT_packed_depth_stencil
  40
  41    Defines a new GL_DEPTH_STENCIL_EXT pixel format.
  42
  43 -  GL_EXT_framebuffer_blit
  44
  45    A simplified glCopyPixels-like feature for copying pixel rectangles.
  46
  47 -  GL_ARB_half_float_pixel
  48
  49    Adds a new half-precision floating point format for image transfers,
  50    such as for glDrawPixels, glReadPixels, glTexImage, etc.
  51
  52 Changes
  53 -------
  54
  55 -  removed GL_HP_occlusion_test (use GL_ARB_occlusion_query instead)
  56 -  removed GL_SGIX/SGIS_pixel_texture extensions
  57
  58 Bug fixes
  59 ---------
  60
  61 -  fixed glxcontextmodes.c datatype problem (bug 5835)
  62 -  fixed aix-gcc build/install bugs (bug 5874)
  63 -  fixed some bugs in texture env program generation
  64 -  glXCopyContext() didn't handle texture object bindings properly
  65 -  glXCopyContext() didn't copy all lighting state
  66 -  fixed FreeBSD config (Pedro Giffuni)
  67 -  fixed some minor framebuffer object bugs
  68 -  replaced dprintf() with \_glu_printf() in GLU (bug 6244)
  69 -  fixed a number of thread safety bugs/regressions
  70 -  fixed a number of GLU tesselator bugs (John Shell, bug 6339)
  71 -  paletted texturing was broken w/ floating point palettes (K. Schultz)
  72 -  lots of assorted framebuffer object bug fixes
  73
  74 Known Issues
  75 ------------
  76
  77 -  Rendering to depth textures will not work. Rendering to
  78    GL_DEPTH_STENCIL textures should work.
  79
  80 Driver Interface Changes
  81 ------------------------
  82
  83 -  Stencil: The Driver.StencilOp/Func/Mask() functions have been
  84    replaced by the two-sided versions: Driver.Stencil*Separate().
  85 -  Render-to-texture: The functions for rendering to textures have
  86    changed.
  87
  88 To Do (someday) items
  89 ---------------------
  90
  91 -  Switch to freeglut
  92 -  Increase MAX_DRAWBUFFERS
  93 -  Fix linux-glide target/driver.
  94 -  Fix lambda calculation for frag progs.
