Most of 38 the work was done by Michal Krol. 39 There's probably a fair number of bugs since this is a pretty large, 40 complicated body of code. 41 <br> 42 The OpenGL 2.0 interface to these features will be implemented in a 43 future version of Mesa, 44 45 <li>GL_EXT_timer_query 46 <br> 47 Used to measure the time of OpenGL operations at high precision. 48 Only supported in the software/Xlib driver at this time. 49 50 <li>GL_EXT_packed_depth_stencil 51 <br> 52 Defines a new GL_DEPTH_STENCIL_EXT pixel format. 53 54 <li>GL_EXT_framebuffer_blit 55 <br> 56 A simplified glCopyPixels-like feature for copying pixel rectangles. 57 58 <li>GL_ARB_half_float_pixel 59 <br> 60 Adds a new half-precision floating point format for image transfers, 61 such as for glDrawPixels, glReadPixels, glTexImage, etc. 62 </ul> 63 64 <h2>Changes</h2> 65 <ul> 66 <li>removed GL_HP_occlusion_test (use GL_ARB_occlusion_query instead) 67 <li>removed GL_SGIX/SGIS_pixel_texture extensions 68 </ul> 69 <h2>Bug fixes</h2> 70 <ul> 71 <li>fixed glxcontextmodes.c datatype problem (bug 5835) 72 <li>fixed aix-gcc build/install bugs (bug 5874) 73 <li>fixed some bugs in texture env program generation 74 <li>glXCopyContext() didn't handle texture object bindings properly 75 <li>glXCopyContext() didn't copy all lighting state 76 <li>fixed FreeBSD config (Pedro Giffuni) 77 <li>fixed some minor framebuffer object bugs 78 <li>replaced dprintf() with _glu_printf() in GLU (bug 6244) 79 <li>fixed a number of thread safety bugs/regressions 80 <li>fixed a number of GLU tesselator bugs (John Shell, bug 6339) 81 <li>paletted texturing was broken w/ floating point palettes (K.
