don't include version.mk from Makefile.common. version.mk's sole purpose
now is to figure out which version of the OpenGL specification is
implemented by the XFree86-provided Mesa and to deduce a likely version of
Mesa from the OpenGL specification implemented.

MesaDemos:
rather than using the pre-built distribution makefiles,
use the automake/configure built makefiles which have
the build dependencies all setup.

While here, fix PR pkg/23003 by moving the version number to version.mk
and including that in the buildlink.
on tech-pkg@ at various times. This means that regardless of what kind of
GL support comes with X11, if a package depends on GL, Mesa 5.0.1 (or higher)
will be installed into ${LOCALBASE}.
Some troubleshooting after the latest patches by Krister Walfridsson.
Default Mesa Version should be 3.4.2, so that people who don't care and have
GL in XF don't need to build the whole thing. If MESA_REQD is set to 5.0.1
(as, for example, by MesaDemos), require version 5.0.1 of MesaLib, gl* etc.
If libGL.so.5 is found to be present on the system, force MESA_REQD to be
5.0.1 to avoid accidental downgrades if MESA_REQD was not specified before-
hand.
Changes reviewed by tron@ (thanks!).
things are more complex than they seem, so until we've figured out how to
do this properly go back to what used to work (ie default back to 5.0.1)
Problems pointed out by tron@ and abs@.
All other Mesa packages assume a default of 3.4.2, so set this here, too.
The reasoning behind this is that 3.4.2 is part of XF, so that users/packages
that don't explicitly need version 5.x don't need to build it.
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
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.
pkgsrc. Instead, a new variable PKGREVISION is invented that can get
bumped independent of DISTNAME and PKGNAME.
Example #1:
DISTNAME= foo-X.Y
PKGREVISION= Z
=> PKGNAME= foo-X.YnbZ
Example #2:
DISTNAME= barthing-X.Y
PKGNAME= bar-X.Y
PKGREVISION= Z
=> PKGNAME= bar=X.YnbZ (!)
On subsequent changes, only PKGREVISION needs to be bumped, no more risk
of getting DISTNAME changed accidentally.
foo-* to foo-[0-9]*. This is to cause the dependencies to match only the
packages whose base package name is "foo", and not those named "foo-bar".
A concrete example is p5-Net-* matching p5-Net-DNS as well as p5-Net. Also
change dependency examples in Packages.txt to reflect this.
${BUILDLINK_DIR}. The consensus on tech-pkg@netbsd.org (2000-09-10)
seems to be to fix the packages that include <GL/xmesa.h> instead of
using a workaround.
already exist. This file is in Mesa-3.4.2, but not in the Mesa included
with XFree86-4.x where the definitions in the file have migrated elsewhere.
We create an empty one in this case to prevent compile errors caused by
source files including xmesa.h and not finding it.
linked from a particular package, and add a pre-configure target to
the buildlink.mk file to more painlessly use buildlink.mk files. A
${BUILDLINK_TARGETS} variable still exists in case a package _must_
define NO_CONFIGURE.
