Make use of a nonce for setting SVG-Edit IDs
option. By default, SVG-Edit behaves as before.
Calling svgCanvas.randomizeIds(true) gives our
behaviour, instead.
Also, sync with latest SVG-Edit (but disable,
for now, manual editing of IDs).
Since we can have several SVG-Edit graphics
on a page, SVG-Edit should assign unique IDs
to elements, and do so in a fashion that survives
re-editing.
To do this, we use a nonce, and record its value in
a custom se:nonce attribute on the <svg> element.
(Is there a better way?).
Also, preserve the custom se:connector attribute for
later editing purposes.
Add a Rack Metal itex endpoint.
Add an itex tool to SVG-Edit.
Disable the foreignObject tool
(at least, for now) as it doesn't
currently play nice with the itex tool.
Further whittling away at differences between
Instiki's and the main branch of SVG-Edit.
Now, the saveHandler is set from within the calling
page.
If the editor was opened from Instiki, choosing "Save Image"
now closes the editor window. To leave it open was kinda confusing.
Also sync with latest SVG-Edit changes.
Thanks to Alexis Deveria. (Though I did fix one small bug.)
My patch-file is now down to a mere 178 lines (a big
chunk of which is Revision 569).
Also, the font-size for foreignObjects defaults to 16pt,
which will be more useful in Instiki.
Pass the SVG to the editor, using
editor.svgCanvas.setSvgString(selected);
instead. (Suggested by Jeff Schiller)
Fix a bug with line and freehand tools caused
by activating foreignObject tool. (Again, fix
due to Jeff)
Sync with SVG-Edit.
Added support so that you can
create new foreignObjects, manipulate
existing ones, and edit their content.
No itex support. You need to use MathML
in there. But it's a start ...
They are now selectable, draggable, resizable
and rotatable.
The MathML content behave strangely when you
resize, but snaps back to its correct size when
you let go of the mouse.
(Resizing the MathML involves changing the font-size
on the containing foreignObject. No interface for
that, yet.)
