this all works now:

```python
from gi.repository import Vips

a = Vips.ArrayDouble.new([1,2,3])
a.get()

a = Vips.ArrayInt.new([1,2,3])
a.get()

a = Vips.ArrayImage.new([c, d, e])
a.get()

ebec31fe4a more careful p->t conversion 
When we convert an image from "p" to "t" in vips_image_wio_input(), zap
start/gen/stop callbacks. This makes vips_region_prepare_to() read from
the "t" rather than trying to gen pixels again.

004c98f296 pngsave interlaced makes a copy of the image 
interlaced png is hard to write: you have to make seven passes over the
image to make the whole file. It advertises itself as sequential, it
needs to only ake a single pass. Therefore, it must take a copy in
memory of the image to write.
