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.

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.

Ensure interlaced PNG input works with libpng16
...
Manually calling png_set_interlace_handling results in the internal
num_rows member of the opaque png_structp not being correctly set.
This appears to be a limitation of libpng so probably needs fixing
upstream before the png_set_interlace_handling call can be re-added.
