-+ * resulting in 18 bytes of non compressed data overhead.

-+ * Files divided into blocks
-+ * 1 bit (last block flag)
-+ * 2 bits (block type)
-+ *
-+ * 1 block occurs every 32K -1 bytes or when there 50% compression has been achieved.

-+ * 32 bits length in bytes.

-+ * The buffer for decompression in place is the length of the
-+ * uncompressed data, plus a small amount extra to keep the algorithm safe.
-+ * The compressed data is placed at the end of the buffer. The output
-+ * pointer is placed at the start of the buffer and the input pointer
-+ * is placed where the compressed data starts. Problems will occur
-+ * when the output pointer overruns the input pointer.
-+ *
-+ * The output pointer can only overrun the input pointer if the input
-+ * pointer is moving faster than the output pointer. A condition only
-+ * triggered by data whose compressed form is larger than the uncompressed
-+ * form.
-+ *
-+ * The worst case at the block level is a growth of the compressed data
-+ * of 5 bytes per 32767 bytes.
-+ *
-+ * The worst case internal to a compressed block is very hard to figure.
-+ * The worst case can at least be boundined by having one bit that represents
-+ * 32764 bytes and then all of the rest of the bytes representing the very
-+ * very last byte.
-+ *
-+ * All of which is enough to compute an amount of extra data that is required
-+ * to be safe. To avoid problems at the block level allocating 5 extra bytes
-+ * per 32767 bytes of data is sufficient. To avoind problems internal to a block
-+ * adding an extra 32767 bytes (the worst case uncompressed block size) is
-+ * sufficient, to ensure that in the worst case the decompressed data for
-+ * block will stop the byte before the compressed data for a block begins.
-+ * To avoid problems with the compressed data's meta information an extra 18
-+ * bytes are needed. Leading to the formula:
-+ *
-+ * extra_bytes = (uncompressed_size >> 12) + 32768 + 18 + decompressor_size.
-+ *
-+ * Adding 8 bytes per 32K is a bit excessive but much easier to calculate.
-+ * Adding 32768 instead of 32767 just makes for round numbers.
-+ * Adding the decompressor_size is necessary as it musht live after all
-+ * of the data as well. Last I measured the decompressor is about 14K.
-+ * 10K of actuall data and 4K of bss.
