FYI, accelerated support for the accumulation buffer is very rare these
days. On pretty much all Macs, and a fair sprinkling of recent Windows
machines, requesting an accumulation buffer will cause software fallback.

These days, one should be performing accumulation operations on a
framebuffer object, using shaders for the more complicated blending
operations.
