Shadow: Use Geometry Shader for better perfs. The 3 cascades are now rendered in a single pass, using 2D array texture and a GS to do the dispatch ("layered rendering"). It's possible to use instancing instead but it requires the AMD_vertex_shader_layer extension which is oddly part of opengl 4.2. 2014-02-10 13:28:02 -05:00			`layout(triangles) in;`
