eb14077ab7 added jitter parameter to lights, currently uses random vectors, which i'm not happy with; added Vector::getPerpendicularVector() which will be used to replace random jitter for lights

5590c533ce Fixed boolean objects to determine if rays start inside or outside the boolean; changed constructors to accept a list of shapes instead of just two shapes; changed parser to accept any number of top-level shapes inside of a boolean shape block; changed scenes/die.fart to reflect this change (a drastic simplification)

86888fa461 changed Scene::calculateLightContribution() to return a Color instead of a double and take into account the color of any semi-transparent objects that are passed through en route to the light source... this leads to shadow colors tainted by the color of the objects through which the light is travelling

84f6b04cd7 removed static const Material::white (had a problem with C++ since the order that the static const constructors were being called in was not correct according to the order that the code depended on them), made Shape constructor use a common default material instead of recreating one every time

6a649ecac7 fixed Lighting to ignore dot products less than 0 for diffuse coefficients; this broke shapes/Subtract again. fixed Material::white to be assigned to by Material() as evidently it was not calling the constructor properly otherwise. added initializer in Material::Material() to set ambient color to white. Scene constructing PointLight instead of a raw Light when loading from a file
