RE: [cgmo-webcgm] changes in DOM specification for redraw control

["Bezaire, Benoit" <bbezaire@ptc.com>]

I tend to agree with Lofton regarding the boolean. Using keywords such as: disableAll, disableStyles, etc... might allow us more control in the future.

 

I find current wording a bit loose though... After a first read, I had the following questions in mind:

- what happens if I change .src

- what happens if I apply an XCF

- do tooltips, highlighting, viewports etc... still work?

 

I think saying "current view" in the description is problematic. We should also clarify if this is a Picture or viewer 'setting'. It's on the Picture interface, so I assume it is meant for the current picture... meaning that if a new picture is loaded, this setting reverts back to the default value. Is that the intent?

Thanks for the drafting assignment, Forrest.

A couple of 
comment and questions:

1.) I wonder if Boolean is the best choice for the 
'state' parameter?  I know that it encompasses all of the functionality 
that we want for 2.1.  But is it possible that there might be a future 
version with more functional choices?  (No opinion ... just a 
question.)

2.) What other sections of the spec are affected?  I 
looked at 2.7 and think it is NOT affected -- redraw() is too detailed there, 
probably.  On the other hand, Ch.8 ECMASCRIPT definitely needs mods. Are 
there any others?  Ch.7 Conformance?  
Appendixes?

Regards,
-Lofton.
