Write codec verbose prints to wrong

[anthony]

Verbose output for output codec is to stdout, not stderr.

Example

Code: Select all

convert -verbose null: -compress none ppm:   >stdout 2>stderr

The file stderr contains... (which was from the read)

null:=> NULL 1x1 1x1+0+0 16-bit DirectClass 0.000u 0:00.000

the file stdout contains

P6
1 1
65535
0 0 0
null:=> NULL 1x1 1x1+0+0 16-bit DirectClass 0.000u 0:00.000

That last line is NOT part of the image and should have been in the stderr file not the stdout.
Other tests (adjusting the verbose setting range) shows that it is the final write that does it wrong.
It causes problems in debugging convert commands in data pipelines.
