Add a workaround for skybox. The problem was with shader-based pipeline with disabled "advanced effects" in options. In this case we don't use RTTs and gl_FragCoord contains values in range of whole window. So fo 2 players we still get gl_FragCoord.y = 0..window_size instead of gl_FragCoord.y = 0..window_size/2. The easiest way to solve it seems to be modulo it by current viewport size. It should be compatible with advanced pipeline as well as single-player games. Atm. I'm not sure if this should be applied to 0.9.2 branch. It should work fine, but needs some testing. 2016-05-08 21:38:24 +02:00			`vec3 eyedir = vec3(mod(gl_FragCoord.xy, screen) / screen, 1.);`
