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

it could try to make a region on a dead image

9febc3ac3e seq could be set on small random images 
images under the disc threshold opened in random access mode from
sequential loaders would have the seq tag set on them, causing
performance problems with vips_resize()

5664a0d9b1 dzsave outputs extra tiles along right and bottom 
the deepzoom spec wants tiles to be written along the right and bottom,
even of those tiles contain no new pixels

6f16a9df71 fix a crash with heavy use of draw 
we were leaving a few bits of the original image around after
vips_image_copy_memory(), including the progress signal ... if earlier images
were freed, perhaps by a GC in a language binding, we could get a dangling
pointer
