jit.qt.movie feature request @colorspace native (constructive criticism please)

Hello

I thought I might repost this in its own thread so it gets attention
from the elves! (happy new year by the way!) Yes I am aware this may
not happen at all, and if it does plan I can wait till 2.0 :P

This was discussed in the uyvy optimization thread:

*feature request below!*

...

it might be nice if there was an attribute @colorspace native which
would also dumpout the colorspace on the rightmost outlet (dumpout
outlet) right before the movie plays its first frame, and load the
movie natively.

This would allow you to :

*Have a fastpath GPU uploading solution that would retain alpha
channel should your quicktime movie have one, or skip right to UYVY
those that need it.

*Decide what to do with the alpha channel should you want to keep it.

I was thinking it might be useful for something like this: Does this
make sense?
