+Subject: [PATCH] reset window placement if last position is out of available
+ display space (#18988)
+
+* reset window if position is out of display space
+
+on initialisation darktable moves the window to the last position even thats outside of the available displays.
+
+_valid_window_placement checks for an overlay with an existing display
+
+dt_gui_gtk_load_config() resets position to default if there's no overlap
+
+* 24 pixel as a border
+
+a border of 24 pixels is used to define the effective area that must be overlapped from the last window position to avoid a reset of position
+
+* stile fixes
+
+one parameter per line
+several const additions
