Description

In 1.5 svgrasterizer, when outputting PNG images, transparent PNGs are created
only for 24-bit PNGs.For cases where size of output image is a concern, it would
be nice if transparent images were created for indexed (8-, 4-, 2-, 1- bit) PNGs
as well.
I believe Thomas DeWeese is the person who wrote PNG encoding code.
