	=== Formats ===		=== Formats ===
	As Avisynth doesn't support natively high bit-depth, a specific format named [[Stack16]] is introduced. The picture is made of two parts, one containing the highest 8 bits (MSB) stacked on top of another containing the lowest 8 bits (LSB) for each pixel. When previewing the video stored in stack16 format, the top part looks quite like the original picture and the bottom one generally looks like psychedelic garbage.		As Avisynth (not AvisynthPlus) doesn't support natively high bit-depth, a specific format named [[Stack16]] aka lsb is introduced. The picture is made of two parts, one containing the highest 8 bits (MSB) stacked on top of another containing the lowest 8 bits (LSB) for each pixel. When previewing the video stored in stack16 format, the top part looks quite like the original picture and the bottom one generally looks like psychedelic garbage.

	Some functions may also use an MSB/LSB decomposition as interleaved pictures, but this format should be considered deprecated and is only supported for backward compatibility.		Some functions may also use an MSB/LSB decomposition as interleaved aka Double-Width pictures, but this format should be considered deprecated and is only supported for backward compatibility.

	Finally, there are a few other formats made specifically for encoding, allowing Avisynth to send more than 8 bits per plane by faking raw data characteristics on the codec side.

			'''v1.27.2, 2015.12.30'''

			* Fixed Dither_crop16 which wasn’t passing the align parameter if there was no horizontal cropping. Thanks to Reel.Deel for making me check.
			* Fixed Dither_srgb_display with autopar=false and 1440×1080 input.
			* Fixed Dither_quantize with reducerange=true, some rare pixel values were wrongly quantized. Thanks to _08 for reporting this bug.
			* Fixed a picture corruption in Dither_bilateral16. Thanks to _08 for reporting what was actually a combination of two different bugs.
