[Lazarus] Gtk2 under X11 new feature - accurate frame size - need users feedback
Finally I've fixed gtk2 under x11 too (qt/qt5 are fixed 2 days ago), now
GetWindowRect() returns correct form size (with frame around) , so
now eg poScreenCenter/poWorkAreaCenter (poWorkAreaCenter is also fixed -
Screen.WorkAreaRect was same as Screen.DesktopRect because of wrong
implementation of SPI_GETWORKAREA) is perfectly centered on screen.
