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
In the Video Sequence Editor, the function "View / Range / Set End Frame" sets the end frame one frame further on the timeline than the current position of the playhead.
Exact steps for others to reproduce the error
Probably related:
Can confirm, will check.
Hm, to me it looks like the drawing of the range is actually wrong.
Note though that it has bee tried to correct this [which has then been reverted for reasons I dont fully grasp... ].
See the following commits:
0e02ad8b642cdcb1c171Maybe @Psy-Fi or @fsiddi remembers why this got reverted?
Regarding
Set Frame Range to Strips: this otoh looks like it actually sets the range wrong since the initial implementation ind4bef6a215(it subtracts 1 from the end for no obvious reason -- possibly to circumvent the drawing issue?)So until we know why the drawing is the way it is, we might want to NOT change the other issue [both would be trivial to do though]
CC @iss
"Set End Frame" is set to next frame, instead of playhead position (VSE)to VSE range drawing off by one for endframe, Set Frame Range to Strips off by one for endframeThis is working as intended. Reason is, because in VSE a frame has "width". Keyframes are point like, so you don't have this issue.
This can't be resolved by mnodifying
strip_jumpoperator, because it wouldn't work correctly.This also can't be resolved by modifying
end_frame_setoperator, because if you set end frame according to what you see in preview, it would not work correctly.Same goes for drawing issue - if you ignore frame width, users would extend strip up tu end frame line, which will result in always rendering black frame.
Only solution would be to make playhead represent the width of a frame, but that would be ugly and perhaps even more confusing.
Will close, since this is working as expected. Thanks for reporting anyway. Will add comment to code to clarify this.
