And if you don't want to read the forum post: he attached a width and
height parameter to the SWF for whatever reason (customer
requirement), and never expected that to influence the behavior full
screen.
So my question actually is:
1) is it a documented behavior, that you can override width and height
with query vars
2) if it's a documented behavior or a "feature", I need to mention in
the fullscreen documentation what effect it will have

That means: if you have the app running at 600x600 without full
screen, and you go into full screen on a 1440x900 screen, the canvas
will remain at 600x600 in the upper left corner of the screen.
Of course you can easily avoid that by NOT passing any value through
query vars into the Laszlo app, but if you look into the forum post
that caused this discussion you'll see that a user got confused by
that behavior.
I was just investigating what's going on to help this guy.

um... so what is the conflict?

Actually it happens on canvas construction, in the construct()
method. Which means, it overrides the values in your <canvas />
declaration within LZX. As a result canvas will - even in full
screen mode - still report the static width & height passed into
the app.

It does seem like a useful feature in case you want to use a swf
embedded in something that is not a browser (although I suppose
you could always write it yourself in code, so maybe it is not
worth maintaining)
Just curious... why does it interfere with full screen mode? I
would think that would happen long after canvas construct...

A user in the forums ran into a problem with full screen mode.
Here's the thread:

Here's the test page as well. The left application scales when
going into fullscree, the right one doesn't. For both the canvas
width & height are set to 100%. The customer wants to use the
following query vars attached to the SWF:
http://www.simplylearnt.com:5080/xmlcrm/slTest.swf?test_id=_-epinfoways&type=share&partner=fachak&width=500&height=400
The usage of the args with the name width and height is
processed by LaszloCanvas.lzs#construct(), here are the relevant
lines (line 307-12)
// Default to arg values
var width = args.width;
var height = args.height;
var bgcolor = args.bgcolor;
delete args.width;
delete args.height;
delete args.bgcolor;
Is that a feature we still use? Looks like it might be used, so
we should probably advise programmers not too attach any query
strings with those names to the SWF, if they plan to use full
screen.
