Vipsvalue_set_blob_free

void
vips_value_set_blob_free (
  GValue* value,
  void* data,
  size_t length
)

Just like vips_value_set_blob(), but when value is freed, data will be freed with g_free().

This can be easier to call for language bindings.

`value`	`GValue`
	GValue to set.
	The data is owned by the caller of the function.
`data`	An array of `guint8`
	Pointer to area of memory.
	The length of the array is specified in the `length` argument.
	The called function takes ownership of the data, and is responsible for freeing it.
`length`	`size_t`
	Length of memory area.
