Version 3.32 - embedded Lout files

[Christopher Wolfe]

On Friday I tested Lout 3.32's ability to include Lout-generated EPS
files in Lout-generated documents.  I had mixed results.

Here is my test log.

Test 1: success
I included 2 Lout-generated EPS files as graphics in an Lout document. 
The resulting file looked OK.  All Lout source files in this test 
contained formatted text; no photos, nothing fancy.

For the following tests, I use photos of houses, converted to EPSF 
format by ImageMagick 6.0.7.  Let's call these files "photo1.eps" and 
"photo2.eps".  I used these photos to mock up a real estate ad a couple 
of months ago, when the first EPS bug was exposed.

Test 2: success
I included photo1.eps as a graphic in an Lout illustration.  The results 
looked OK.  Text below the photo appeared.  (I saved the output as 
"house1.eps" for further testing.)

Test 3: success
I included photo1.eps as a graphic in an Lout document.  The results 
looked OK.  Text above and below the photo appeared.

Test 4: success
I included photo1.eps and photo2.eps as graphics in an Lout document. 
The results looked OK.  I see 2 photos of a house in the output.  Text 
above and below the photos appeared.

Test 5: failure
I included the results of test 2, house1.eps, as a graphic in an Lout 
document.  GhostScript 8.54 reports errors, unfortunately.  It shows the 
results, but the text that should be right below the graphic is at the 
bottom of the page.  This worked fine in Lout 3.31 with my patch on 8/24.

For reference, test 5's files are attached... except for the photo. 
house1.eps is 750 KB, so I spared the list a large attachment.  I will 
gladly forward it to whomever is interested.

Test 6: failure
Repeated test 2 for photo2.eps, generating house2.eps.  I included 
house1.eps and house2.eps in an Lout document.  The errors are more 
pronounced in these results.  This worked fine in Lout 3.31 with my patch.

Test 7: success
Include house1.eps in an Lout illustration.  Results look OK.

Test 8: success
Include house1.eps and house2.eps in an Lout illustration.  Results look OK.

Conclusion:
Lout 3.32 performed better than base Lout 3.31 in these tests.  I 
consider it an improvement.

I am rather unique in that I desire Lout Illustrations and final EPS 
output, as in tests 7 and 8.  I guess that the majority of Lout users 
desire page-sized PostScript documents, as in tests 5 and 6.  So the 
above issues warrant further study.

I'll follow up and ask one of my in-house PostScript experts to diagnose 
the error in tests 5 and 6.  I am hoping their answer will be more than 
"reapply the patch from 8/24".
