Write a standard TIFF header into buf as a data string, return number of bytes copied.
<p>
Only the byte order of the TIFF header varies, the values written for offset and tag are constant, i.e., independent of the values possibly read before a call to this function. The value 0x00000008 is written for the offset, tag is set to 0x002a.<p>
