When a dock widget is moved between high DPI screens, it's native
position is calculated and applied. The calculation falls back to a
mapping without high DPI, if the dock widget's initial position cannot
be mapped to a QScreen.
A warning was emitted in that case, to inform the user about a
potential screen misconfiguration (e.g. a physical screens not being
mapped exactly next to each other, leaving a gap). Despite of the
warning, the position calculation safely falls back to non high DPI.
The warning also kicks in when the dock widget's top left position
is located outside a screen, hence being invisible.
Since calculating an invisible top left position is possible without
high DPI mapping, this patch replaces the warning with a
debug message.
