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.

201cf02d85 libimg: transparency fixes. 
img.convert doesn't make opaque pixels transparent.
gif decoder considers palette pixels opaque.

a0a18277da libimg: tiff: Don't rely on EOI tag at the end of the strip. 
Reference implementation (libtiff) has a workaround: precalculate data
size of the strip and don't rely on EOI tag of specific bit length.

This allow to read some invalid TIFF LZW images by my old scanner.

6cf659fe71 libimg: add img.from_file, refactor img.convert. 
Add new function, img.from_file: gets file name and returns decoded Image.
Make img.convert code less spaghetti: use jump table, not a chain of jmp's.
