42 * The Command Block allows multiple command buffers to be processed with one run.
43 * Command Block commands have to obey to the following rules:
44 * CR_CMDBLOCKBEGIN_OPCODE - must be the first command in the command buffer, specifying the command block start
45 * CR_CMDBLOCKEND_OPCODE - must be the last command in the command buffer, specifying the command block end
46 * If not placed accordingly, CR_CMDBLOCK** commands are ignored.
47 * Server copies the command block buffer commands to its internal storage
48 * and processes them with one run when the command block end is signalled
