mostly a bugfix release
other changes:
- updated GL/gl_mangle.h file
- use glPolygonOffset in gloss demo to avoid z-fighting artifacts
- updated winpos and pointblast demos to use ARB extensions
- disable SPARC normal transformation code
package for clean-depends-list purposes.
While here, also remove the no longer necessary CFLAGS after previous commit
in MesaLib and also add distinfo for MesaLib for non Mesa-5.0.
At the same time, move Mesa and friends to LOCALBASE rather than X11BASE, so
that they can be installed regardless of XF version. Introduce MESA_REQD variable
that can be set to 5.0, thus allowing systems with XF4 to indicate that the
provided version is not good enough.
All packages using Mesa, MesaLib, glu or glut will get a PKGREVISION bump
over the next few days.

Phew!
when the capabilities of the running X11 server differ from the X11 server
on the system for which the package is meant. We now try to guess the
Mesa version number based on which OpenGL specification is implemented.
Separate out the logic into its own file, Mesa/version.mk, and use it in
MesaLib's and glu's buildlink2.mk files.
Note that Mesa/version.mk should only be used by the Mesa packages and is
_not_ for general use.
X11PREFIX != X11BASE (xpkgwedge is installed). Introduce a new variable
MESA_REQD that defaults to "3.4.2" and represents the version of Mesa/GL
needed by a package. MESA_REQD is intended to be used by package Makefiles
or by buildlink2.mk files.
It should now be possible to update this package to the latest release
(5.0), and have it work on:
* XF86-3.x with or without xpkgwedge
* XF86-4.x with xpkgwedge
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.

smaug% grep 'MesaLib.*3.4' */*/Makefile*

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)

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out of date - it was based on a.out OBJECT_FMT, and added entries in the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.
