 no - i kept things brief, so as not to dominate the postings here:
you've very kindly filled in the blanks, and given far more
information than even i was aware of, which is great.

 ... all of which is accessible via DOM manipulation, via the W3C-DOM-
specified functions through the <canvas /> element.   use of which has
resulted in the creation of a very powerful _python_ library which re-
presents those SVG Canvas functions.  fillRect. saveContext.
translate.

 demo of end-result usage can be seen here:

 yes, it could.  personally i wouldn't recommend the javascript bit.
it's too dreadful. :)

 ah - no, it won't.  isn't.  pyjamas apps are the proof that that
isn't the case.  pyjamas applications contain, at the absolute basics,
_one_ HTML file comprising... about eight lines, the most important
two bits being a "meta" tag naming the pre-compiled application, and a
"script" tag with bootstrap.js which knows about the aforementioned
"meta" tag.  that's _it_.  the rest can be done _entirely_ using
declarative-style programming.

 but... if you _want_ to, that "loader" file can be a full-blown PHP
app: just as long as that meta tag is there, and the bootstrap.js is
there, the pyjamas app can be initiated "on top of" the PHP page.
just like any other javascript can be run and can begin to manipulate
the DOM.  so it's just a matter of degree.  you can either specify
almost everything in "text" HTML/CSS or you can do entire DOM-
manipulation or anything in between, to suit _your_ personal
preference.

 i must not be explaining this very well, for which i apologise.

 :)  yehhs... and then people complain when it doesn't "look good".
interesting neh?

 hence a reason why i'm advocating to "leverage" the incredible power
of the technologies which _have_ had vast amounts of money/effort
poured into them, with very little effort spent on the "leveraging"
bit.
