fteqw/engine/d3d/d3d11_shader.c
Spoike 95266f8215 d3d11 fixes. mipmapping implemented, vertex streaming more performant. Still behind the d3d9 renderer. 
Fixed d3d11 vs d3d9 conflicts when switching renderers.
Fixed hlsl-less d3d9 lava.
Added gl_specular_fallback to override the default gloss level.
Added these cvars to give more control over imported/dlight lighting r_shadow_realtime_dlight_ambient r_shadow_realtime_dlight_diffuse r_shadow_realtime_dlight_specular r_editlights_import_radius r_editlights_import_ambient r_editlights_import_diffuse r_editlights_import_specular. Effective value of r_editlights_import_specular is now 1. Was 4.
Fixed spot/cube/smap lights.
