A headless receiver has no window manager, so a windowed window is meaningless there — the screencast should simply fill the screen. The renderer now goes borderless fullscreen automatically when SDL runs the KMSDRM backend, and --fullscreen forces the same behavior in desktop sessions. The video keeps its aspect ratio via SDL_SetRenderLogicalPresentation(LETTERBOX): a 4:3 desktop on a 16:9 TV renders with black bars instead of a stretched picture, the cursor is hidden, and the clear-before-draw keeps the bars black. Verified live on a 3440x1440 monitor: the --fullscreen receiver window covered the entire display while a 4:3 synthetic feed rendered with pure-black pillarbox bars (Y=0/SAT=0) and a saturated-red center (V=254). meson test 5/5 in both build configurations.
