Sorry about the delays, but here is the changed source code. I also 
included some demo files and some documentation(part of the reason for 
the delays).

To fix the "upside down pigment" problem with patterned_blur, add, 
multiply, and exponent, change this line in the functions 
doPostPatternBlur(), doPostAdd(), doPostMult(), and doPostExp():
        Loc[0] = (DBL)x/width;
        Loc[1] = (DBL)y/height;
to this:
        Loc[0] = (DBL)x/width;
        Loc[1] = 1-((DBL)y/height);

Due to problems with the .zip version, here is the .sit version. If you 
don't have StuffIt Expander, you can get it here:

Dear Christopher James Huff,I want to consult a question:
I want to output the intersection point I(x,y,z) in x(ix,iy), y(ix,iy) and
z(ix,iy) as an ancillary image.I only find the function of PP_Depth in
"pprocess.inc" ,and I did not find the function of output the intersection point
I(x,y,z).Can you give me an example about output the intersection point or offer
an advice? So sorry to disturb you. Expecting you reply.
#version unofficial MegaPov 1.1;

#include "pprocess.inc"
“global_settings {

  assumed_gamma 1.0

  post_process{

    PP_Depth(DepthMin,DepthMax)

    save_file concat("pp_",output_filename(0))

  }

}”

Regards
