[Gimp-print-devel] units_branch

[Robert Krawitz]

It is soooooo tempting to minimize the differences between mainline
and branch by sticking

#define stp_dimension_t int
#define stp_resolution_t int

in gutenprint.h on the mainline and merging the resulting changes
(with a few other such things). The idea of using #define rather than
typedef would be to avoid creating a new type (and thereby changing
the API) on the mainline.

While merging hasn't generally been too troublesome, we have had a few
tricky items, and this would cut down on that a lot. There would
still be a few things we can't avoid (such as format strings), but it
would greatly reduce the amount of differences.
