Does this rely upon the underlying OpenGL implementation/driver supporting glBlendEquation() (i.e. OpenGL 1.3 or 1.2+GL_ARB_imaging)?
Yes, blendEquation depends on the glBlendEquationEXT extension function. If the extension is not supported, an exception with the message unknown OpenGL call glBlendEquationEXT, check for GL_EXT_blend_minmax or GL_EXT_blend_subtract or OpenGL 1.4 should be thrown, not a segfault. This is a bit mysterious... Cheers, S.
