coin310 — New Features in Coin v3.1.0

This is a brief summary of the new features in Coin v3.1.0:

• Default transparency type for SoGLRenderAction changed from SCREEN_DOOR to BLEND.
• SoBase will not keep a list of unnamed / empty named nodes any more. This is both an optimization and improves conformance to SGI / TGS Inventor.
• SbTesselator does better when handed certain polygons, due to improved precision in internal calculations.
• Resource usage pressure significantly lower for common case scene graphs with regard to mutex allocations. A not entirely uncommon problem on MS Windows systems for huge scene graphs was that the run-time system ran out of available mutexes -- this is now very unlikely to happen.
• Builds with G++ and MSVC will have C++ exception support enabled by default.
• SoSceneManager render callback can be set to NULL to disable it.
• Non-power-of-two textures are automatically supported if the OpenGL driver has that feature.
• No other intentional differences in semantics, other than for any bugs fixed.
