   HDR: Special Considerations for Transparency?
  Greetings,I'm attempting to impliment full HDR into my project, and excluding a few bugs, it's been working great.  Now, the one problem I've been having has to do with alpha blending and transparency.  In certain situations, when additive/alpha blended sprites layer over each other, the transparent areas flicker and show up slightly opaque.  I'm guessing that there's floating point inaccuracies going on, but I'm not sure what's a good way to fix that.  Are there considerations I can make to ensure that this stops happening?  If so, what are they? Thanks,Zach.
