+	Lossy-Compressed Pixel Formats
+	
+	The following pixel formats can be used to reduce memory bandwidth and memory footprint involved in large-scale pixel data flow, which can have benefits for battery life and thermal efficiency.
+	Similar to lossless pixel formats, they work by dividing pixel buffers into fixed-width, fixed-height, fixed-byte-size blocks. Pixel buffers allocated using lossy formats have reduced memory footprint than their lossless equivalents; this reduced footprint may or may not result in loss of quality depending on the content of the individual block. Hardware units (video codecs, GPU, ISP, etc.) attempt to write a compressed encoding for each block using either a lossless or lossy algorithm.  If a block of pixels is successfully encoded within its pre-defined memory footprint, then the lossless alogrithm is applied; if the encoded block of pixels exceeds the pre-defined memory footprint then the lossy algorithm is applied.  Each compressed pixel buffer has a separate area of metadata recording the encoding choices for each pixel block.
+	
+	IMPORTANT CAVEATS:
+	Some devices do not support these pixel formats at all.
+	Before using one of these pixel formats, call CVIsCompressedPixelFormatAvailable() to check that it is available on the current device.
+	On different devices, the concrete details of these formats may be different.
+	On different devices, the degree and details of support by hardware units (video codecs, GPU, ISP, etc.) may be different.
+	Do not ship code that reads the contents of lossless-compressed pixel buffers directly with the CPU, or which saves or transfers it to other devices, as this code will break with future hardware.
+	The bandwidth benefits of these formats are generally outweighed by the cost of buffer copies to convert to uncompressed pixel formats, so if you find that you need to perform a buffer copy to covert for CPU usage, it's likely that you would have been better served by using the equivalent uncompressed pixel formats in the first place.
