A request for the maximized state has two potential origins:
1. The compositor, through an xdg_toplevel configure event. In this case we update the window state and size accordingly.
2. The application or Wine itself, by changing the window style. When we detect such a style, we make a request to the compositor to set the maximized state. The compositor will then eventually reply with a configure event, and we continue with case (1). Note that the compositor may deny our request, in which case we will also sync the window style accordingly.
An acknowledged maximized state imposes very strict constraints on the size of surface content we can present. We are careful to not violate these constraints, since otherwise the compositor will disconnect us. --- dlls/winewayland.drv/wayland_surface.c | 88 ++++++++++++++++++++++---- dlls/winewayland.drv/waylanddrv.h | 6 ++ dlls/winewayland.drv/window.c | 41 +++++++++++- 3 files changed, 123 insertions(+), 12 deletions(-)
