Add thirdparty directory and incorporate GLU tessellator

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Kenneth Russell]

For new rendering algorithms being incorporated into WebKit, the polygon tessellator from the OpenGL utility library is needed. Some small modifications were needed from the original sources in SGI's OpenGL Sample Implementation (http://oss.sgi.com/projects/ogl-sample/). It is desired to be able to build these sources on any platform that wishes to utilize these new algorithms. For this reason a 3rdparty directory is being added to WebCore and the GLU tessellator sources within.

Patch

From the ChangeLog:

This directory is intended to contain copies of third-party libraries used by WebCore, in particular those which may require some modification in order to incorporate.

No tests at this time; these sources are being added in preparation for incorporating other code which uses them, at which point the code will be exercised and testable.

We really need to teach the stylebot to ignore third-party code.

nit: for new files that are added, it is nice to strip out mention of
the functions included in the new file since they aren't that helpful
when reading a ChangeLog entry like this.  you really just want to
know the set of files being added and the function names just add
noise.  (this was the advice that darin adler gave to me once upon
a time.)

Will do this upon landing.
