* - emulate spot (see testmode and dirtdash - other textlayer transparency issues in dirtdash is also spot related?)
* - texture u/v mapping is often 1 pixel off, resulting in many glitch lines/gaps between textures
* - tokyowar tanks are not shootable, same for timecris helicopter, there's still a very small hitbox but almost impossible to hit
