   destination (basename is still there but deprecated)
 - new _UNBUFFERED sequential mode saves memory in some important cases
 - start vips_conv() as a simple wrapper over the old convolution functions
+- new optimize_coding param for jpeg write produces optimal Huffman tables,
+  thanks Lovell 
 
 3/7/13 started 7.34.2
