Summary: pix_writer write rgba images - osx
Initial Comment:
I must insert a [pix_rgba] before [pix_writer] to have the good image written.
It seems [pix_writer] writes rgb images even if it receives yuv data.
osx.6.8
gem from current git

Message:
Maybe I was not clear enough.
If I use [pix_writer] just after [pix_video] I get a totally distorted
image.
Exactly the same if I use [pix_image] on a rgb image, and then [pix_yuv]
and then [pix_writer].
It looks like [pix_writer] is not testing the format of the texture and
assume it's rgb even if it's not the case.
The expected behavior is to have the same result with
[pix_snap]+[pix_writer] and [pix_write]

what is the expected behaviour?
i don't think you can natively write YUV-images in TIF; JPEG uses their own
colorspace anyhow.
