29599e00eb avoid NaN in mapim 
We were not avoiding NaN in float transform images, leading to segvs in
some cases.

Thanks afontenot

d8ed630d77 better 8/16 bit casting for pngsave 
pngsave was just using the image format to decide whether to save as 8
or 16 bit PNG. With this patch it checks Type as well.

This means that eg. a uint32 image tagged as sRGB will save as png8, but
a uint32 image tagged as RGB16 will save as png16.

3ad7363104 heifsave: add option to control subsample_mode 
Defaults to no subsampling when Q>90 for consistency with jpegsave.

Deprecate VipsForeignJpegSubsample enum, replace with more generic
VipsForeignSubsample.
