When I enable fog in perfly and then take a screen snapshot using the
pfuSaveImage function, with readsource() set to SRC_FRONT, the captured image
has a much different fog density than the on-screen image. How is fog
implemented on the RE2, and what is the proper way to get the same image in a
snapshot that I see on the screen? Do I need to readsource() and lrectread()
from multiple buffers and somehow blend the images?

Thanks
