Log is attached.
implemented a fixed function fallback for water, but it is disabled
because of extreme distortion artifacts (it would need to use a cubemap
for perspective correction)
implemented two-pass rendering of water and refraction surfaces, this
enables blendfunc of the first layer to work properly, the old path is
still present but disabled
