Performance problems and memory leaks when using SoBufferRegions.

The classes SoBufferRegion and SoGLRenderAction had two issues related to the usage of the SoBufferRegion and the bug introduced by this OpenGL extension:

1) SoGLRenderAction was creating and destroying the buffer region object at each frame.
2) SoBufferRegion did not call the function wglDeleteBufferRegionARB to free the memory.
