Due to an oversight in the multi-precision feature,
TJCompressor.srcBuf12 and TJCompressor.srcBuf16 were not set to null
in TJCompressor.setSourceImage(YUVImage) or
TJCompressor.setSourceImage(BufferedImage, ...). Thus, if an
application set a 12-bit or 16-bit packed-pixel buffer as the source
image then set a BufferedImage with integer pixels as the source image,
TJCompress.compress() would compress from the 12-bit or 16-bit
packed-pixel buffer instead of the BufferedImage. The odds of an
application actually doing that are very slim, however.
