SVN changelog

• Added engine-based quantization of sunlight shadowmaps parameters, which eliminates annoying flickering during player movement/daytime change.
• Vertical sun shadows during noon enabled (was disabled in previous builds because of strong flickering)
• Lowered r_shadows 2 shadowmap resolution, since flickering is removed
• Shadowmap size can be tweaked on per-location basis uting map settings script. W1m4 gains double size shadowmap that way to cover large scale heights.
• Shadowmap settings are tweaked for better performance (lowered resolution where possible, added focus offset)
• Scrollblend shader effect used on water surfaces rewritten to support glossmaps/diffuse distortion as well (makes water to look a bit more dirty)- r_water 0 looks not so bad now
• Added animated water textures for all water surfaces (brook water on w1m1/w1m2, great lake of w1m4, lake of nachtholm, dungeon water)
• Added sunlight specular effect for water
• Water environment specular effect now based on sunlight code
• Fixed bug with lightsource shader ignoring vertex alpha (which leads to ugly water edges on water surface lit by magic light)
• Sunlight shadows now cast upon sprites and blended surfaces
• Some tiny bugs fixed

Optimizations:

• Enabled depth first render trick (render depth-only, then normal render) as it seems to give performance on all maps (w1m4 gains about 10% FPS)
• Tweaked location size of w1m6
