render: Enable clipping for zero-sized rectangles Battle for Wesnoth apparently relies on being able to disable rendering of UI elements by setting the clip rectangle to be empty. Resolves: https://github.com/libsdl-org/SDL/issues/6896 Fixes: 00f05dcf "render: only enable clipping when the rectangle is valid" Signed-off-by: Simon McVittie <smcv@collabora.com> (cherry picked from commit 8ad043fc38f09e5a88aca266ae6b70f572d66a1f)
