If no text is selected, this is the same as passing the caret offset, since the selection range is already where we want it.
However, if text is selected, this allows the caller to replace it, just as it would be when pasting using the keyboard or GUI.
Note that this doesn't break any existing expectations because TEXT_OFFSET_CARET was never supported for this method previously.
This allows us to remove the DeleteText call from Android SessionAccessibility::Paste.
This separate DeleteText call was causing problems because it could result in the deletion and the insertion happening in two separate ticks, resulting in incorrect events.
Now, this should always happen in a single tick.

Introduce a gecko live region changed event and fire it from within content.
This way it gets coalesced in the case of many insertions/deletions.
Also, rely on text insert/delete instead of reorder because there can be cases
where the text in a leaf changes as opposed to a tree mutation.
We get text insert/delete on mutations too, so that should cover it.

This revision implements a simple way to set cache domains from XPCOM, which is
crucial for testing caching granularity.

Most OS APIs want a cluster when they ask for a "character", except ATK.
Rather than altering BOUNDARY_CHAR, I added a new BOUNDARY_CLUSTER.
Aside from being less risky and causing less churn, there are cases internally where we want to move a TextLeafPoint by character; e.g. to explicitly move to the next/previous Accessible or to move to the next/previous character in an abstract way without worrying about Accessible boundaries.
Calculating clusters is more expensive, so it doesn't make sense to move by cluster in those cases.

This revision implements the ARIA rowgroup role in Gecko. Previously, Gecko was
using roles::GROUPING for multiple types of groups and disambiguating them
in various places. This revision unwinds that while maintaining present
functionality.

Previously the `boolean` type was also declared using a `bool` typedef in
xpidl, meaning that both were used in various places. This patch standardizes
on the built-in `boolean` type, removing the typedef.

This revision adds a Gecko GRID role, matching the ARIA 'grid' role, and
implements its platform mappings. It then remaps the ARIA 'grid' role to the
Gecko GRID role. Finally, this revision removes the expected-fail for the
relevant formerly-failing web platform test and updates existing tests.

This revision implements the mapping for the ARIA 1.2 emphasis role, which was
unsupported in Firefox until now. This change addresses a web platform test
failure. To accomplish this, the revision adds the WAI-defined role, adds a role
enum value, adds platform mappings, and adds a markup role mapping. The change
requires a new static atom for the word "emphasis," also added in this revision.
Finally, this change removes the expected wpt failure and updates other tests.

This patch does several things:
1. Remove virtual cursor doc accessible member.
2. Remove state-keeping nsAccessiblePivot implementation and replace it
with something that is much more similar to the native Pivot
interface.
3. Move nsIAccessiblePivot implementation to xpcom and rename it
xpcAccessiblePivot.
4. Delete mochitests and introduce browser tests.
5. Make new xpcom implementation work on remote accessibles as well.

This includes AccessibleHandler, HandlerProvider, IGeckoCustom and the IAccessible2 COM proxy dll.
Even with the new architecture, we still use IAccessible2, but we no longer need a COM proxy because we aren't using COM across processes ourselves.
If clients want to use IAccessible2 across processes, they're responsible for registering a COM proxy themselves as with all other IAccessible2 applications.
Alternatively, they can rely on the IAccessible2 COM proxy which is included with Windows 10 and later.
