Use GLib's i18n support instead of copying and pasting that logic into its own header. This deprecates the vips/intl.h header in favour of glib/gi18n.h.

/* relational.c --- various relational operations
|
|
*
|
|
* Modified:
|
|
* 26/7/93 JC
|
|
* - >,<,>=,<= tests now as (double) to prevent compiler warnings. Should
|
|
* split into int/float cases really for speed.
|
|
* 25/1/95 JC
|
|
* - partialized
|
|
* - updated
|
|
* 7/2/95 JC
|
|
* - oops! bug with doubles fixed
|
|
* 3/7/98 JC
|
|
* - vector versions added ... im_equal_vec(), im_lesseq_vec() etc
|
|
* - small tidies
|
|
* - should be a bit faster, lots of *q++ changed to q[x]
|
|
* 10/3/03 JC
|
|
* - reworked to remove nested #defines: a bit slower, but much smaller
|
|
* - all except _vec forms now work on complex
|
|
* 31/7/03 JC
|
|
* - oops, relational_format was broken for some combinations
|
|
* 23/9/09
|
|
* - gtkdoc
|
|
* - use new im__arith_binary*() functions
|
|
* - more meta-programming
|
|
* 23/6/10
|
|
* - oops, moreconst and moreeqconst were the same
|
|
* 4/11/11
|
|
* - redone as a class
|
|
* 1/2/12
|
|
* - complex ==, != were broken
|
|
* 16/7/12
|
|
* - im1 > im2, im1 >= im2 were broken
|
|
* 17/9/14
|
|
* - im1 > im2, im1 >= im2 were still broken, but in a more subtle way
