    gdk: always populate GDK_AXIS_{X,Y} in merged event history · 0c448518
    hemidark authored
    Since GdkTimeCoord stores only axis values, prior to this change,
    if a device didn't report GDK_AXIS_X or GDK_AXIS_Y, the history
    attached to merged motion events wouldn't contain any positional
    information.
    
    Commit 60122760 already addressed
    this issue for devices without tools by storing the event position
    in GdkTimeCoord using GDK_AXIS_X and GDK_AXIS_Y and augmenting the
    GdkTimeCoord's axis bitmask accordingly.
    
    This change generalizes that workaround to all devices. Note that
    if a device DOES report values for GDK_AXIS_X and GDK_AXIS_Y, those
    values won't be overwritten.
    
    Closes #4809
