4b422db243 Add keep_rgb option to prevent RGB -> YCbCr conversion during JPEG write 
libjpeg automatically converts RGB to YCbCr by default.  Add a keep_rgb
option to disable libjpeg's automatic conversion of RGB images during
write.

e572722479 Allow configuring JPEG restart marker interval on save 
libjpeg allows specifying the marker interval either in MCU blocks or in
MCU rows.  Support both, via separate parameters, rather than requiring
callers to do the math.

36bcc0a898 Support saving PDF with different X and Y resolution. 
Add a `dpi` parameter to the PDF save function, which accepts
a tuple with X and Y dpi.
This is useful for converting tiffg3 (fax) images to pdf,
which have split dpi like (204,391), (204,196) or (204,98).
