Bug #56750 for PDF-Reuse: Bug #41805 - Patch to make prJpeg understand Grayscale etc.

Dear Lars, I have been using PDF::Reuse for a couple of months now and have found it very useful. I particularly like the quick start-up time compared to PDF::API2 because my application often needs to create a single small PDF file on a single invocation of the perl script. Thanks you for your efforts in producing it. I am not using the 'reuse' features but generating files from scratch so I have noticed the same problem already reported as bug number 41805 - that prJpeg() does not understand Grayscale jpg files. I have enhanced prJpeg to do this and as this means it needs to call Image::Info, also integrated the logic to automatically assess the image size and return it. For 99.9% of uses, the Image::Info overhead is the same but just moved from the caller to the module. The changed subroutine still keeps the original behaviour (and speed) if you call it in the original way. I have attached the patch file for you to assess if you wish to integrate it with the distribution. Although I think the issue and patch are relevant to any platform, my platform is: Hardware: Sun E3500 OS: Solaris 10.00 on Sparc Perl 5.10.1 PDF::Reuse 0.35 Thanks for your work in developing this package - I hope you consider my contribution useful.
