Hi Igor,

image_filter_transparency [on|off]
default is on.

The directive allows to disable image transparency in GIF and
palette-based PNG to improve image resampling quality. True color PNG
alpha-channels are always preserved despite this setting.
Did not check grayscale PNG, however, I believe it should be handled
as truecolor PNGs.
