Modern desktop environments can render icons at very large sizes, especially with high DPI screens. Providing a 32x32 pixel bitmap is nowhere near sufficient anymore. When displayed in GNOME shell the QEMU icon looks awful, having been scaled up to at least x4 its base size. This is compounded by the fact that the BMP file doesn't do transparency, so while we've removed white pixels, we still have anti-aliased nearly-white pixels which make the logo look appalling on black backgrounds. Loading a high resolution PNG icon addresses both problems, but requires use of the extra SDL2_image library. Signed-off-by: Daniel P.
