08dcf29b10 add vips_rotate() 
vips_similarity() was a little hatrd to discover, so add vips_rotate()
as a more obvious name for it

29e05dabaf icc_import attaches the input profile if used 
icc_import can take a fallback input profile in case the embedded one is
broken or missing. If we use the fallback profile, this change attaches
it to the output image.

This means that icc_import will always output an image with the icc
profile that was used to import it. This helps to make the behaviour of
`thumbnail` more consistent.

20d840e6da fix a crash with delayed load 
If a delayed load failed, it could leave the pipeline only half-set up.
Sebsequent threads could then segv.

Set a load-has-failed flag and test before generate.

eefb2dad98 improve rounding in convi intize 
We were rounding up with ceil() when intize-ing convolution masks.
However, the vector path has a true range of (1.0, -1.0], so a mask with
1.0 as the max (for example) was actually triggering the overflow detector
and falling back to the C path.

Round up with ceil(x + 1) instead, so 1.0 (for example) will be mapped
to 0.5 and won't overflow.

01eed391ab add sync locks to vips_sink() 
vips_sink() used to just fire off threads willy nilly -- this could
cause problems with sequential images if a worker fell too far behind
the pack

copy over the area locking mechanism from vips_sink_memory(): new
threads are now stalled if an old thread has not finished

24c07cfde2 revert an accidental ABI break 
the new window manager code in 8.6.1 changed the prototype of an internal
function which was visible in the public API

this patch renames the function, adds it to an internal header instead,
and adds a stub for the old prototype
