Coin 2.5.0 released

Systems in Motion is proud to release v2.5.0 of the Coin 3D graphics library. Coin 2.5.0 is a minor release. It extends the functionality of previous versions of Coin 2 in upward compatible ways. It also fixes bugs and problems found in releases 2.0.0 through 2.4.6, and includes updates to the documentation. The API and ABI of the library have been considerably extended for this version, but not in any way that could conflict with older versions of Coin 2.
