Subject: [PATCH -perfbook] defer: Retouch SVG files for browser compatibility
 (2nd attempt)

In <text> elements which are misplaced when viewed in a browser,
there are "transform" directives of the form:

    transform="scale(-1)"

(indicating rotation of 180 degrees), and attributes of:

    writing-mode:tb-rl

(top to bottom, right to left: Normally used in vertical text in
Asian languages.  "lr-tb" is the normal choice in English.)

By manually removing those transform directives and replacing
"tb-rl" with "lr-tb" by a text editor; then ungrouping, rotating,
and moving those text elements by Inkscape 1.1.1; browser-compatible
SVGs have been obtained.

Regrouping of edited text elements have been done as a final stage.

Hi Paul,

I've not figured out what operations corrupted those text elements in
RCUspacetime.svg.
So take this fix as a "happens to work" kind of thing.

Do you have any clue as to why those text elements have 180 degree
rotation and vertical writing mode?

I guess you copied such a text element to RCUusecases.svg and edited
and copied it in Inkscape.  So I suspect RCUusecases.svg was corrupted
from the very beginning.

After this update, you should be able to edit both SVGs by Inkscape
as you'd like, I suppose.

        Thanks, Akira
