- dzsave basename param now called filename, so you can use .dz as a
destination (basename is still there but deprecated)
- new _UNBUFFERED sequential mode saves memory in some important cases
- start vips_conv() as a simple wrapper over the old convolution functions
3/7/13 started 7.34.2
- lower priority for Matlab load to reduce segvs from Mat_Open(), thanks

/* histogram cumulativisation
*
* Author: N. Dessipris
* Written on: 02/08/1990
* 24/5/95 JC
* - tidied up and ANSIfied
* 20/7/95 JC
* - smartened up again
* - now works for hists >256 elements
* 3/3/01 JC
* - broken into cum and norm ... helps im_histspec()
* - better behaviour for >8 bit hists
* 31/10/05 JC
* - was broken for vertical histograms, gah
* - neater im_histnorm()
* 23/7/07
* - eek, off by 1 for more than 1 band hists
* 12/5/08
* - histcum works for signed hists now as well
* 24/3/10
* - gtkdoc
* - small cleanups
* 12/8/13
* - redone im_histcum() as a class, vips_conv()
