add libbpg-0.9.2, an image formatting library designed to replace JPEG
when quality or file size is an issue, to the packages collection.

	BPG (Better Portable Graphics) is a new image format.  Its purpose is
	to replace the JPEG image format when quality or file size is an
	issue.  Its main advantages are:

	+ High compression ratio.  Files are much smaller than JPEG for
	similar quality.

	+ Supported by most Web browsers with a small Javascript decoder
	(gzipped size:  71 KB).

	+ Based on a subset of the HEVC open video compression standard.

	+ Supports the same chroma formats as JPEG (grayscale, YCbCr 4:2:0,
	4:2:2, 4:4:4) to reduce the losses during the conversion.  An alpha
	channel is supported.  The RGB, YCgCo and CMYK color spaces are also
	supported.

	+ Native support of 8 to 14 bits per channel for a higher dynamic
	range.

	+ Lossless compression is supported.

	+ Various metadata (such as EXIF, ICC profile, XMP) can be included.
