blueprint for better resampling about papercrop

[GoogleCodeExporter]

I do not use any resampling in the code. The output images are directly 
rasterized from the poppler PDF library.
I could do supersampling + resampling but it would improve only scanned 
documents (or bitmap fonts), so it would be low priority for me. 
PaperCrop support only rasterized PDF outputs at the moment.
I would like to implement preserving original PDF objects, but I don't have 
much time these days.
Sorry,

just FYI, if aliasing is problematic for most pdf files on your ebook devices, 
it could mean that the output resolution setting doesn't exactly match your 
ebook device.
For instance, most major ebook readers' optimal resolutions are slightly 
smaller than 600x800. (I don't remember exact resolution. My ebook reader 
support fullscreen.)
It is actually very tricky to find the right resolution that gives one-to-one 
pixel mapping, but it is possible. This setting is critically important to get 
satisfactory results.

Optionally added supersampling functionality at the svn repository. 
(Binary will be uploaded in a month after adding a few new features.)
