A neater solution! In Python it should be something like:

remove vips7 stuff from API
...
You must now include vips7 support explicitly with
#include <vips/vips7compat.h>
in your code just after including `vips.h`.
The old vips7 names, such as `Rect`, were starting to cause problems
with other packages like opencv.

make hist_equal output format match input format
...
If the input image was ushort but had only uchar range, hist_equal would
output a uchar image, thanks to hist_norm's auto-clip feature. Make sure
this can't happen bu casting after the norm.

see https://github.com/jcupitt/libvips/issues/268
also fix a couple of small range problems
- scale by 255, not 256, to avoid an overflow
- cum hist includes the current value, so sum to <= target, not < target
