Bug 1431: Fix NewtCanvasAWT resize on X11, broken since commit ad38d1559854985b1131e5b6c7274a392b5bc265

Commit ad38d1559854985b1131e5b6c7274a392b5bc265 introduced XTranslateCoordinates(..) to savely validate
the client-space window position against the parent (root).

Totally missing in this change was the NEWT child window case
since it always used the root-window as the destination.

This change tracks the parent-window (valid parent Window or NULL)
within the JavaWindow struct and either uses the parent-window
if available or the root-window for XTranslateCoordinates(..).
This results in the proper client-space position.

Validated against
- TestGearsES2NewtCanvasAWT
- TestBug1431NewtCanvasAWT

on Debian 12 w/ Java17.
