egl/wayland: Damage INT32_MAX x INT32_MAX region for eglSwapBuffers
If we're not using EGL_EXT_swap_buffers_with_damage, we have to damage the full extent. EGL operates on buffer coordinates, but wl_surface.damage takes surface coordinates. EGL doesn't know the buffer transformation (rotated or scaled) and can't post accurate damage in surface coordinates. The damage event however is clipped to the surface extents so we can just damage the maximum rectangle. In case of EGL_EXT_swap_buffers_with_damage, the application knows the buffer transform and is expected to pass in rectangles in surface space. https://bugs.freedesktop.org/show_bug.cgi?id=70250 Cc: "10.0" mesa-stable@lists.freedesktop.org
