- added VIPS_ARGUMENT_APPEND to help control arg ordering - added argument priorites to help control arg ordering
- generate has a 'stop' param to signal successful early termination - generate has a 'stop' param to signal successful early termination
- added optional output args, eg. x/y for min - added optional output args, eg. x/y for min

- clip next? - lintra_vec next

bodge it for now, fix properly after we merge bodge it for now, fix properly after we merge
- don't do vips_image_write() at the end of a pipeline, instead try:
g_object_set( object, "output", t );
ie. replace the output object
fails due to "assign once only" rule ... we need "don't assign after
written" instead

/* clip.c ... convert BandFmt, clipping values
*
* Author: Nicos Dessipris
* Written on: 07/03/1991
* Modified on:
* 04/05/1992 JC
* - works for char, uchar too
* - floating point code removed from integer clip operations
* - uses nint() instead of own rounding code
* - calculated the number of >255 clips for float/double input
* incorrectly
* - rejects complex input correctly now
* 27/4/93 JC
* - adapted to work with partial images
* - nint() removed, now just +0.5
* - im_warning code removed
* 30/6/93 JC
* - adapted for partial v2
* 31/8/93 JC
* - now detects and prints over/underflows
* 27/10/93 JC
* - unsigned integer clips now faster!
* - falls back to im_copy() correctly
* 5/5/94 JC
* - switched to rint()
* 18/8/94 JC
* - now uses evalend callback
* 9/5/95 JC
* - now does complex too
* 11/7/95 JC
* - now uses IM_RINT() macro
* 10/3/01 JC
* - slightly faster and simpler
* - generalised to im_clip2fmt(), all other clippers now just call
* this
* 21/4/04 JC
* - now does floor(), not rint() ... you'll need to round yourself
* before calling this if you want round-to-nearest
* 7/11/07
* - use new evalstart/evalend system
* 26/8/08
* - oops, complex->complex conversion was broken
* 27/1/10
* - modernised
* - gtk-doc
