- Basic and PSSM shadow renderer are now deprecated - There is now one processor and its filter conterpart for each light type - created an abstract shadow processor that hold the common shadowing code. It's totally independent of the shadow technique used. - extracted the CompareMode and FilterMode enum to their own files. - renamed FilterMode enum to EdgeFilteringMode - refactored the shader code, to avoid duplicate code. all shadow related code is now gathered into Shadows.glsllib and Shadows15.glsllib. - added spot light Shadows - removed the ShadowCamera class as it was not used. - removed "pssm" in the naming of classes, shader and shader libs since it's not relevant anymore git-svn-id: https://jmonkeyengine.googlecode.com/svn/trunk@9971 75d07b2b-3a1a-0410-a2c5-0572b91ccdca
