dt_dev_pixelpipe_process_rec(): avoid integer overflow on big images
Initially reported by frogs (@IRC). Thanks!

Fixes a crash on 135MP+ images when zooming in (100%) on bottom right corner of image.

TODO: find a way to automatically check ALL the similar code and make sure that all of it handles this situation correctly.
Add support for Canon 7DMkII sRaw/mRaw modes
New routine dt_view_image_only_expose to display only an image.

This will be used by the print module.
Rename some lightroom types to avoid name clashes with the print module.
Initial revision of the print module.

This is a new module. It requires CUPS to send the print job to the
printer queue. The module offers a way to add some margin, select
the paper size, the print queue. It also support a printer/paper ICC
profile.
