Add shadow filtering (PCF) option. Fix ugly shadow saturation in old lighting mode. Fix fancy water shader. Fix camera matrix computation. Support scissoring of camera frustum. Optimise vertex skinning. Inline various matrix functions. Support filtering of the list of submitted models before a rendering pass, for more precise culling. Optimise water renderer (fixes #721, based on patch by ortalo). Use scissoring when generating reflection/refraction textures. Skip reflection/refraction texture generation when no water is visible. Render alpha-blended objects differently (fixes #434). Reduce shadow swimming effects. This was SVN commit r9814.
