Adjust for ideally cropped pdfs

[GoogleCodeExporter]

What steps will reproduce the problem?
I use Bliss utility to crop pdf, ie remove footer and header 
(http://sourceforge.net/projects/briss/). I took 9-11 commission report for the 
test (you can google it). I did not any additional adjustment, allowed the 
utility to crop as it found it best.

What is the expected output? What do you see instead?
I wanted to see almost no space between pages (on Windows Pdf XChange-Viewer 
adds very small space between pages, almost unnoticeable. In apv the space is 
visible (a couple of text lines). I tried to change boxes in the settings, 
seems like didn't help. 

What version of the product are you using? On what operating system?
apv-0.3.1dev7.apk

It would be easy to add an adjustment to the spacing between pages.

The next dev release will have an option to put no space--it's there in the 
code.  Actually, I still see one line, and I don't know where that comes from.  
Maybe it's round-off error.

Just a thought... If the app is based on muPdf (CMIIW), can be compare this 
result with some viewer based on muPdf in Continuous mode? If the result is 
better, there would be possible to look at how this utility did this.

Comparision of SumatraPDF with PDF XChange Viewer and FoxIt

- Took fullreport.pdf 
- At about page 45-46 one line ends with ".. prepared to " and the next line is 
 "contact...". Zoom 300%
- From baseline to baseline the space is 45-46 pixels (all viewers)

The space between baseslines of different pages
SumatraPDF 94 pixels, 
PDF XChange Viewer 92 pixels
Foxit 92 pixels (cropped interpage space since it can't be disabled in the 
program)

I think that the difference (2 pixels = 4% of line-to-line) is not a big deal. 
Also the croppers sometimes don't crop perfectly so your single line between 
pages is probably unavoidable.

Well, try dev9.  I'm uploading it now.

By the way, by "one line", I meant one pixel line, in case that wasn't clear.

Tested, worked like a charm. Measured with screenshot, for "None" the numbers 
(relative) are similar to the ones mentioned about other viewers. 
Sorry about "one line" :)
