The fact the it works with UVPov and not with the SuperPatch tells me that
there might be something wrong with the API hooks in the SP and Ron should
look into it anyway.

Probably.  I really should get a registered copy of Moray someday; I don't
feel right using it for testing after my evaluation period expired.  Well,
okay, I'll do it just this once.

Well, I just spent a few minutes looking at it and it appears I'm sending
the moray control DLL exactly the same information as the official version,
but it's just not getting to Moray.  Why this should be, I don't know.  I
even tried it with a version built from the new 3.1g windows code and it
didn't make a difference.  I'm somewhat stumped.

Hi Ron Parker, you recently wrote in moray.win:

Hmmm. Is the complete source code available for download so that I can
debug it? Or where can I get a compiled debug version that fails. I
can take a look at what's failing.

There's source for the version that's out there on my website at
http://www2.fwi.com/~parkerr/superpatch/ .  You'll also need a copy
of the Windows 3.1a source to build it; I'm not sure if that's still
available or not.  If not, you can probably use the 3.1g source.
I've included a VC6 project file, because that's what I use.

Hmmm. I just ran my DLL in the debugger, under SuperPatch control, so
to speak (The Superpatch was the debuggee). The only strange thing I
saw was that when I start a render, POV calls the POVDisplayPlot
functions instead of the POVAssignPixel function. Since POV returned a
GUI Extension version of 101, it should be calling the PixelAssign
function.

Strangely enough, when the GUI Extension starts the render, neither
POVDisplayPlot nor POVAssignPixel is called....

It looks like I'll have to get SuperPatch to compile and see that I
can debug that.

I compiled it with 3.1g source and found the bug. 

The problem is an out-of-date Render.C in the SuperPatch source.

You need to add the following line at line 1371:

	  POV_ASSIGN_PIXEL (x, y, Current_Line[x])

just after the call:

      plot_pixel(x, y, Current_Line[x]);

I just compared the render.c from 3.1a, 3.1g and SuperPatch and both
official version have the line, but the SuperPatch version is missing
this line.

Thanks, Lutz.  Sounds like another merge bug.  I'll fix it ASAP.
