Some png file in my project using pngQuantize will throw `quantize failed QUALITY_TOO_LOW`

[clijiac]

Some png file in my project using pngQuantize will throw quantize failed QUALITY_TOO_LOW, cause build failed.

can we have a fallback option that when some compress failed we can use original image or use another compress method instead(in my case, change to pngLossless worked) to make build continue?
