When the display mode changes such that the screen height changes, we'd like our windows to keep their position relative to the top-left of the primary screen. That's how WinAPI's coordinate system works and we want the WinAPI position of the window to not change just because the display mode changed. Unfortunately that's not achievable in Cocoa. Cocoa keeps the window stationary relative to the screen it's on, not necessarily the primary screen, and it's sometimes relative to the bottom-left and sometimes the top-left of that screen. So, what we do instead is queue an event to get the back end to reassert the WinAPI position of the window. This is queued before Cocoa can adjust the Cocoa position of the window which would queue a WINDOW_FRAME_CHANGED to the back end and mess up the WinAPI position. The back end's reassertion of the WinAPI position won't be processed by the Cocoa thread until after Cocoa has adjusted the position and will thus override it. It will also discard any wrong WINDOW_FRAME_CHANGED that may have been queued. Signed-off-by: Ken Thomases <ken@codeweavers.com>
