Currently, the "Widescreen Hack" option in the D3D plugin only works
correctly when playing a native 4:3 aspect ratio game on a 16:9 aspect
ratio display. The hack simply stretches the game aspect ratio from 4:3 to
16:9 regardless of the aspect ratio of the current window. When using the
hack, this causes 4:3 games to have an image that is too skinny on 16:10
displays. It is also completely non-functional on native 16:9 games.

It should be modified to be called "Aspect Ratio Hack". It should adjust
from the games native aspect ratio, either 4:3 or 16:9, this is already
detected correctly when using the "Auto" aspect ratio, so this isn't a
problem. And the aspect ratio should be "hacked" to that of the display,
4:3, 5:4, 16:9, 16:10, or anything.
