Method makePointLitSpecular

shared/java/ImageFilter.java:1008–1016

Create a filter that calculates the specular illumination from a point light source, using alpha channel of the input as the height profile of the surface (to approximate normal vectors). @param x The location of the point light (X component) @param y The location of the poi
