DopeSheet Drawing Tweak:

Keyframes for locked channels are now shown faintly so that it is
possible to easily distinguish between keyframes for locked channels
and unlocked channels. Hopefully this solves the problem where you
have some keyframes selected, and try to move them but forget that
those channels are locked (without any feedback other than a single
icon).

Thanks for pointing out this problem Ronan Zeegers!
