- Introduced PresentSync module to manage display synchronization. - Updated love.run() to handle display changes and resizing events with PresentSync. - Enhanced FrameCap logic to accommodate PresentSync requirements. - Modified VSync to report effective states and handle driver quirks. - Updated options menus to reflect PresentSync availability and restrictions. - Added tests to validate PresentSync functionality and its interaction with VSync settings. should address issue #1910 and issue #1958
