• Rename cut operator to split

@Peter Fog (tintwotin) No need for report if you are not fixing bug, just improving interface

This report was linked to a patch, which cleaned up the polls giving the impression of a broken sidebar. It also exposed the mentioned meta strip functions. In the VSE chat I posted a suggestion on how to make the Meta Strip range more clear and with your line of code the "Return" button could be implemented. So all of these things could be solved, but I'll leave it up to you guys.
The patch: https://developer.blender.org/D6913

There are a couple of bugs/unfinished implementation of the Meta Strips in the Sequencer:

Always report one bug per report.

At that time there may not have been a context menu where you can find the edit meta strip operator. Now there is.

The UI could show this more clearly, but it's not a bug and doesn't belong in the bug tracker.

We generally don't put normal operators in the sidebar or properties - I see no reason for an exception here.

When toggle to open the Meta strip, no active strip is selected and it breaks the sidebar panel:

@Sybren A. Stüvel (sybren) I agree with your goto rejection.
I have refactored seq_render_image_strip(), same for seq_render_movie_strip() in old uncommited patch.
Later I was looking for this goto use-case and apparently it is 'acceptable' equivalent to finally: statement, so I thought that perhaps this was thought through...

Please extend the patch description; take a look at Ingredients of a Patch. Currently the patch is presented as a "refactor", but it also changes how proxy images are handled, so it's more than just refactoring existing code.

Continued in D6883

Closing this quick hack, the feature was implemented by @Alessio Monti di Sopra (a.monti) and made its way into master.

@Paul (Thirio) The Text Block Anchors icons mentioned above are now included in Blender. Maybe 'anchor' is a better name than 'origin'?

Abandoning this in place of this patch which just moved the Add Modifier to the Add Menu instead: https://developer.blender.org/D6876

Looks good to me!

cut_multicam needed to be renamed to split_multicam.

Has been reported before [long standing issue], see T36263: Pasted strip doesnt have F-Curve keyframes from the original, will merge these reports... (and update T64682: Video Sequence Editor (Sequencer) Module accordingly)

In 2.79 it turns pink, not sure if it renders same as now...
I am fine with how it is now, but I think it works by accident.. it is still marked as invalid in C I think..

@hudson barkley (snuq) did you intentionally made cross effects non-overlaping? It shouldn't work like this... Though we can make a feature out of this bug.

While I can see this might seem like a bug.
