what are those svv, svvc, svvf objects in R2/View?
I never heard them, never saw them in any document?
I saw them in Nick's no-rebol-in-title-bar.r script:
http://www.rebol.org/view-script.r?script=no-rebol-in-title-bar.r
They hold default values for VID?

Shorthand names for the various System data structures that support
View, eg:
>> system/view/vid = svv
== true

And the reason for their existence is not just typing speed...

Wow! A huge speed difference, thanks for explaining it.
It is correct for all paths,
>> system/view/resize-border
== 4x4
>> s: now/precise loop 10'000'000 [system/view/resize-border] difference
>> now/precise s
== 0:00:02.906
>> s: now/precise loop 10'000'000 [svl] difference now/precise s
== 0:00:00.329
