docs: convert articles to reructuredtext
This uses the previously added scripts to convert the documentation to
reStructuredText, which is both easier to read offline, and can be used
to generate modern HTML for online documentation.
No modification to the generated results have been done.

However, the (unix) shared +library version is still 1.5 (i.e. libGL.so.1.5.xxxxxx). Bumping the +shared library version to 2.x would cause linking problems with existing +OpenGL applications. Since OpenGL 2.x is backward compatible with OpenGL +1.x the shared library version number doesn't have to be incremented +(which would indicate an incompatible ABI). + +Other OpenGL vendors name their OpenGL 2.x libraries libGL.so.1.0.xxxxx +for the same reason. + +New features +------------ + +- OpenGL 2.0 and 2.1 API support. +- Entirely new Shading Language code generator. See the `Shading + Language <../shading.html>`__ page for more information. +- Much faster software execution of vertex, fragment shaders. +- New vertex buffer object (vbo) infrastructure +- Updated glext.h file (version 39) +- Updated glxext.h file (version 19) +- GL_MAX_DRAWBUFFERS is now 4 (software rendering) so "multiple render + targets" are really supported. + +Bug fixes +--------- + +- Fog was errantly applied when a fragment shader was enabled (bug + 9346) +- glPush/PopClientAttrib didn't handle VBO bindings correctly (bug + 9445) +- With 32-bit Z buffer, the fragment Z of lines and points was + sometimes wrong. +- GL_POST_CONVOLUTION_ALPHA_BIAS/SCALE was broken. +- 1D convolution state could effect 2D image transfers +- Overlapping glCopyPixels with negative Y zoom didn't work (bug 10521) +- Fixed a number of framebuffer/renderbuffer reference counting bugs +- Fixed a few bugs in software-emulated alpha planes +- Assorted minor bug fixes in glCopy/DrawPixels, glPixelZoom, etc. +- Assorted DRI driver bug fixes. +- Fixed a number of bugs that prevented "depth-peeling" rendering from + working. + +Internal code changes +--------------------- + +- Old array_cache module replaced by new vbo module. All geometry + rendering is now cast in the form of vertex buffer objects. +- Massive changes to the Shading Language compiler and related state. +- Vertex/fragment shaders are compiled into GPU instructions and + programs very similar to GL_ARB_vertex/fragment_program. +- Vertex and fragment programs are executed with the same code now. +- The SSE-optimized vertex program path has been removed since it + didn't support more than 12 temp registers, didn't support + branching/looping, etc. + +To Do (someday) items +--------------------- + +- Switch to freeglut +- Fix linux-glide target/driver. +- Improved lambda and derivative calculation for frag progs. + +Driver Status +------------- + +:: + + Driver Status + ---------------------- ---------------------- + DRI drivers varies with the driver + XMesa/GLX (on Xlib) implements OpenGL 2.1 + OSMesa (off-screen) implements OpenGL 2.1 + Windows/Win32 implements OpenGL 2.1 + Glide (3dfx Voodoo1/2) implements OpenGL 1.3 + SVGA unsupported + Wind River UGL unsupported + DJGPP unsupported + GGI unsupported + BeOS unsupported + Allegro unsupported + D3D unsupported |
