We currently write invalid sBIT entries for indexed PNGs, which by PNG specification[1] must be 3-bytes long. The values also are capped at 8 for indexed-color PNGs, not the palette depth. This patch fixes both of these issues previously fixed in the decoder, but not the encoder. [1]: https://www.w3.org/TR/png-3/#11sBIT Regression since: c125860892e931d9b10f88ace73c91484815c3a8.
