PDF page size consistency

[jpt13653903]

From Mark Geisler:

Love this utility! Would make one recommendation:

Would like option for all PDF pages to be the same size based on the maximum extents of the biggest gerber file extrema rather than the data extrema on each page for each gerber file. Also, have the same origin for the data on the pages rather than centering the data on the page.

Thanks.

Mmm...

I don't want to do that by default, but there's no reason I can't make that another command-line option. Should be easy enough...
