e532373af8 libimg: can save 32 bit png

459cb3ec5b libimg: Improve support of transparent PNG images.
* Support grayscale images with alpha channel.
* Support rgb images with transparent color.
* Process 'tRNS' chunk (simple transparency).

Transparent png images were already supported for color type 6, which
is RGBA. Now indexed images (color type 3) can also have transparency
via 'tRNS' chunk data.
