So far, only screen coordinates (`ATSPI_COORD_TYPE_SCREEN`)
and coordinates relative to the widget's top-level window
(`ATSPI_COORD_TYPE_WINDOW`) were supported.
In at-spi 2.30, a third coordinate type, describing
coordinates relative to the widget's immediate parent,
was added: `ATSPI_COORD_TYPE_PARENT` (commit: [1])
This commit adds the handling to convert to and
from that coord type as well and unifies the
existing handling to convert to/from screen coordinates
by introducing two static helper methods
(`AtSpiAdaptor::translateToScreenCoordinates` and
`AtSpiAdaptor::translateFromScreenCoordinates`) and
making use of those wherever conversion needs to
be done.
In addition, also add a check to only handle
requests using a coordinate type that is one of those
that is actually supported instead of returning
incorrect values (for the case that new coord types
should be introduced in AT-SPI in the future).
