135481 - Active Accessibility: need method to scroll screen to specified MSAA node

Status: RESOLVED FIXED

(SeaMonkey :: General, defect, P2)

Description

[Aaron Leventhal]

One of the screen reader vendors has requested this feature. We need to take a
look at what's involved.

Essentially, the want to take an IAccessible, and call some method on it, to
have Gecko scroll the screen to that location.

We might be able to use selection to do this.

Attachment: Adds scrollTo(boolean scrollTopLeft) method to ISimpleDOMNode

Since no one's using ISimpleDOMNode yet, I wish to change it to add this
method.
Our other COM accessibility interface IAccessible is defined by Microsoft and
has no method to do this. 

I've added the method ISimpleDOMNode::scrollTo(boolean scrollTopLeft) and
changed the GUID of ISimpleDOMNode to make sure no one gets messed up if they
are using the old ISimpleDOMNode.

If the boolean scrollTopLeft is true, the item is always moved to the top left
corner of the screen.

If the boolean scrollTopLeft is false, the view is scrolled minimally or not at
all, in order to display the item.

topembed+ as it is required by Freedom Sci for JAWS compatibility with Gecko
