The 0 A.D. product logo is 256×128 pixels, i.e. a 2:1 ratio.
The Wildfire Games company logo is 256×32 pixels, i.e. a 8:1 ratio.
When showing the watermark, the numbers are 190×88 i.e. 2.16:1 and 207×28 i.e. 7.39:1, which doesn't really matter for text, however, the 0 A.D. circle is noticeably squeezed, which looks rather poor. This patch tweaks the number so the correct aspect ratio is preserved.
