The image based Source Patches (Image, Movie, Video) have a checkbox
setting called "Disable Color Correction". While I know what those
words mean I don't know precisely what that checkbox is meant to do
(and so far have not found it documented).
I've made a comp that does some image processing on QT movies input
using the Movie Loader patch and I find that the luma on the output
side is too bright (brighter than expected based on what the comp is
doing) when "Disable Color Correction" is enabled. Also, after
disabling this checkbox and saving the comp I find the checkbox(es) is
re-enabled upon re-opening the saved comp.
