Correct Oni's sprite-drawing for widescreen resolutions

[Iritscen]

There is ​a fix on PCGamingWiki for the drawing of sprites such as weapon sights in widescreen resolutions. The Daodan DLL could accomplish this much more elegantly. So far, the DLL only has a fix for talking heads in widescreen resolutions, as far as I know.

Daodan has [graphics] displayenum patch that should already properly handle this stuff with all display modes reported as supported from the OS.

Clarification: the patch above is "to make proper aspect ratio for weapon sight and some lighting effects" (​source). (I have edited the original ticket to clarify this.) The patchers already know that the AE unlocks widescreen resolutions, but apparently certain sprites drawn on-screen are getting stretched in these wider resolutions. This was also a problem in the Mac Intel build when Feral unlocked widescreen resolutions — weapon sights, lens flares, and fly-in portraits were getting stretched. Their patch alters an aspect ratio represented as a float constant within Oni's code. While I know that fly-in portraits are supposed to be fixed in the Daodan DLL, I haven't tested the other effects mentioned above but presumably they're out of aspect ratio or these guys wouldn't still be patching them after installing the AE.
