rewrite im_bandmean() in terms of recomb()? just use [0.33, 0.33, 0.33]
no, bandmean is OK, just move to conversion
move im_point_bilinear() to deprecated? or convenience?
can we document several classes in one gtk-doc page? doesn't look like it
argh
our choice is then just document the C API, which means making the C wrapper
mandatory, or to make a separate header for every operation
why doesn't vips_add() appear in the docs? curious
try
$ vips join
... usage ...
join: too few arguments
VipsObject: parameter in1 to VipsJoin not set
VipsObject: parameter in2 to VipsJoin not set
VipsObject: parameter direction to VipsJoin not set
why do we have four errors? shouldn't we stop after the first one?
- try an area operation, like conv, VipsArea? oops no haha what name should we

* VipsAdd:

* @out: output image

* This operation calculates @in1 + @in2 and writes the result to @out.
*
* If the images differ in size, the smaller image is enlarged to match the
* larger by adding zero pixels along the bottom and right.
*
* If the number of bands differs, one of the images
* must have one band. In this case, an n-band image is formed from the
* one-band image by joining n copies of the one-band image together, and then
* the two n-band images are operated upon.
*
* The two input images are cast up to the smallest common type (see table
* Smallest common format in
* <link linkend="VIPS-arithmetic">arithmetic</link>), then the
* following table is used to determine the output type:
*
