- indexed that table entry, or it provides a pointer to another\r
- table that indexes more bits of the code. op indicates whether\r
- the entry is a pointer to another table, a literal, a length or\r
- distance, an end-of-block, or an invalid code. For a table\r
- pointer, the low four bits of op is the number of index bits of\r
- that table. For a length or distance, the low four bits of op\r
- is the number of extra bits to get after the code. bits is\r
- the number of bits in this code or part of the code to drop off\r
- of the bit buffer. val is the actual byte to output in the case\r
- of a literal, the base length or distance, or the offset from\r
- the current table to the next table. Each entry is four bytes. */\r
