Add -jpegopt optimize option support to utils
New option 'optimize=y' for utils that take a -jpegopt param,
pdftocairo and pdftoppm. This corresponds to the cjpeg -optimize
flag, and slightly reduces the size of the output jpeg but uses
additional cpu and memory.
New jpegOptimize boolean in splash/SplashBitmap WriteImgParams.
New setOptimize method on goo/JpegWriter taking a boolean.
Update manpages for new option.
