buildlink2.mk files back into the main trunk. This provides sufficient
buildlink2 infrastructure to start merging other packages from the
buildlink2 branch that have already been converted to use the buildlink2
framework.
buildlink.mk simply include the others. This allows distributing the
various tests for whether that part of Mesa is in the base X11R6 into the
relevant buildlink.mk file.
Bug fixes:
- deleting the currently bound texture could cause bad problems
- using fog could result in random vertex alpha values
- AA triangle rendering could touch pixels outside right window bound
- fixed byteswapping problem in clear_32bit_ximage() function
- fixed bugs in wglUseFontBitmapsA(), by Frank Warmerdam
- fixed memory leak in glXUseXFont()
- fragment sampling in AA triangle function was off by 1/2 pixel
- Windows: reading pixels from framebuffer didn't always work
- glConvolutionFilter2D could segfault or cause FP exception
- fixed segfaults in FX and X drivers when using tex unit 1 but not 0
- GL_NAND logicop didn't work right in RGBA mode
- fixed a memory corruption bug in vertex buffer reset code
- clearing the softwara alpha buffer with scissoring was broken
- fixed a few color index mode fog bugs
- fixed some bad assertions in color index mode
- fixed FX line 'stipple' bug #420091
Changes:

Invent a variable MESA_VERSION in Mesa/Makefile.common and use it.
Changes:
New:
- fixed some Linux build problems
- fixed some Windows build problems
- GL_EXT_texture_env_dot3 extension (Gareth Hughes)
Bug fixes:
- added RENDER_START/RENDER_FINISH macros for glCopyTexImage in DRI
- various state-update code changes needed for DRI bugs
- disabled pixel transfer ops in glColorTable commands, not needed
- fixed bugs in glCopyConvolutionFilter1D/2D, glGetConvolutionFilter
- updated sources and fixed compile problems in widgets-mesa/
- GLX_PBUFFER enum value was wrong in glx.h
- fixed a glColorMaterial lighting bug
- fixed bad args to Read/WriteStencilSpan in h/w stencil clear function
- glXCopySubBufferMESA() Y position was off by one
- Error checking of glTexSubImage3D() was broken (bug 128775)
- glPopAttrib() didn't restore all derived Mesa state correctly
- Better glReadPixels accuracy for 16bpp color - fixes lots of OpenGL
conformance problems at 16bpp.
- clearing depth buffer with scissoring was broken, would segfault
- OSMesaGetDepthBuffer() returned bad bytesPerValue value
- fixed a line clipping bug (reported by Craig McDaniel)
- fixed RGB color over/underflow bug for very tiny triangles
Known problems:
- NURBS or evaluator surfaces inside display lists don't always work
out of date - it was based on a.out OBJECT_FMT, and added entries in the
generated PLISTs to reflect the symlinks that ELF packages uses. It also
tried to be clever, and removed and recreated any symbolic links that were
created, which has resulted in some fun, especially with packages which
use dlopen(3) to load modules. Some recent changes to our ld.so to bring
it more into line with other Operating Systems also exposed some cracks.
+ Modify bsd.pkg.mk and its shared object handling, so that PLISTs now contain
the ELF symlinks.
+ Don't mess about with file system entries when handling shared objects in
bsd.pkg.mk, since it's likely that libtool and the BSD *.mk processing will
have got it right, and have a much better idea than we do.
+ Modify PLISTs to contain "ELF symlinks"
+ On a.out platforms, delete any "ELF symlinks" from the generated PLISTs
+ On ELF platforms, no extra processing needs to be done in bsd.pkg.mk
+ Modify print-PLIST target in bsd.pkg.mk to add dummy symlink entries on
a.out platforms
+ Update the documentation in Packages.txt
With many thanks to Thomas Klausner for keeping me honest with this.
