== Sequencer ==

Added enhancements by blendix (Patch #4919: Insert sequence effect between)

It adds the following things:
- You can add a sequence strip afterwards in the middle of an effect chain
(you have to move strips around before, so that there is "room" for it.
Blender will ask you then, if you want to add in between or after the
selected strips)
- In the case you messed it up and want your effect strips to be reassigned in
a different way, there is the new "R"-key. Just select three arbitrary
strips and press "R". If you don't create a cycle, those will be connected
to a new effect chain.
- Fixed freeing of imbufs on changes to properly take into account dependencies. An example of a simple case that went wrong is one image strip with two
glow effects, changing the parameters of the first glow strip will not
result in any updates. Basically only direct dependencies were taken into
account, which resulted in the image preview not being updated in some cases.
- Let the sequencer detect an active sequence strip if none is defined, to
get rid of annoying error messages when trying to add an effect to a
selected sequence strip right after loading a file.
- Delete is less destructive. If you delete somewhere between other strips,
Blender now tries to relink in a reasonable way.
- The active sequence strip is now displayed with a light instead of a dark
outline, which makes it easier to spot, and is especially useful for the
tools using the active sequence strip.
- Ability to view the final result when editing inside meta strip.
The channel button was modified to also allow negative numbers,
where -n is n levels up the meta stack. There is probably a nicer way to
specify this, instead of (ab)using the channel button, but this seems to
work quite efficient.
- Also a small bugfix: don't crash on loading files from newer versions with
an unknown effect strip.
