Subject: [PATCH 124/147] a11y atspi: translate coords for GetOffsetAtPoint the
 right way
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The coordinate type for "GetOffsetAtPoint" describes the
coordinate type of the input coordinates and
`QAccessibleTextInterface::offsetAtPoint` expects the
coordinates in screen coordinates.

Therefore, if window-relative coordinates are given,
the screen coordinates of the window need to be added
(not subtracted) to the window-relative coordinates of the point
in order to calculate the screen coordinates of the point.

Fixes: QTBUG-105281
Pick-to: 6.4 6.3 6.2
Change-Id: I5517335c0c0d6a47b8c45c7e4f8f8b5a91f0fcd7
