Here is is a version of Slackware-14.0's 'mesa' package which has been rebuilt
with the parameter "--enable-shared-glapi" to the configuration.
This results in an added library: libglapi.so. This library is used by some
games. So far I found only one: "Trine 2" which requires this library in order
to run.

If you do not own "Trine 2" then there is no reason to upgrade your mesa with
my modified package.

If you *do* upgrade mesa and you installed proprietary graphics drivers from
NVIDIA or ATI, then you will have to re-install those drivers after the mesa
package upgrade or else you won't have OpenGL acceleration anymore!

The mesa package is meant for a 32-bit Slackware system. You will find a 32-bit
"compat32" package for a 64-bit Slackware multilib system in the "multilib"
subdirectory.
