Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?

Short description of error
Grease Pencil is not the same/consistent scale through multiple editors (Movie Clip Editor & U/V Image Editor vs. Video Sequence Editor & Node Editor) on the same GP Layer.

I am not sure if the additional things I have in here in the videos below are relevant to this or are completely different issues.
Exact steps for others to reproduce the error

Just tested this with 2.76 so either this is not known or not a bug, oh well... I put all this effort in I might as well...

P.S.
I am not to sure if the Grease Pencil is only intended to be used in 3D for animation or if you will be able to still (in 2.80) animate in 2D in 2D Editors.
This line from blender's wiki concerns me tho: "The new Object will be used only for 3D view, including new functionalities. For 2D modes (VSE, IMage Editor, Node Editor, etc) the current grease pencil code will be used and renamed as Annotations." wiki.blender.org
..."Restoration of simple GP "Annotation" functionality for 2D editors."... [Differential D2889 ](https://developer.blender.org/D2889) I hope I'm misunderstanding this.
I checked https://developer.blender.org/project/board/62/ to see if this (observation) is known or not. I hope this is correctly.
Hope I did everything right, as this is my first time reporting a bug.
Any feedback or questions are welcome.

Thanks for your report. There are really 2 sets of issues here, so I'll deal with each one by one.
1) Different Scaling in Different Editor Types
It is not really a bug that the sizes of elements are different in different editor types. In fact, it is an unfortunate and unavoidable consequence of some fundamental differences between the ways that the different editors are set up.
For example:
However, in theory it shouldn't be a problem at all, since strokes from each of these three editor types shouldn't be showing up in the other editors at all, as each one should be taggng its strokes as being of a different type (so that they can get rendered correctly). Why exactly that fails is a topic for discussion, but the workaround is simple: Just don't use the same GP datablock across different editor types! (TBH, I really don't understand why people do anything otherwise :)
2) GP Support in 2.8 (3D vs 2D, etc.)
TBH, the situation here is still a bit of a mess and is very much WIP. First I'll go over what the current situation is, then I'll cover what the eventual plan is, and finally, why things are the way they are.
Current Situation (GP Branch):
Eventual Plans:
As mentioned in a few other places, GP-like support will be returning to all other (2D) editors eventually. However, to avoid confusion, we will be calling that functionality 'Annotations' instead.
Non-3d-art use cases in the 3D view need to be reviewed.
Why - How did we end up in this state, etc.:
For an example of the current manpower limitations, over the past few weeks, we've basically been spending everyday basically tracking down and fixing a neverending stream of crashes and bugs arising from 1) the new functionality and integration with previously unintegrated systems, and 2) have to fix/update our code several times a day, 5 days a week, in response to a constant stream of code churn due to the big depsgraph-related cleanups (atm, barely a day goes by without at least another 2 things breaking there and needing attention)
Second, we're currently working in a branch (based off 2.8), that already has a large number of non-trivial changes in it.
Thank you for your (very well documented) response, you answered all my concerns and I look forward to using the new GP (once it gets merged).
