ShaderState: 'Update' vertexAttribMap on enable
ShaderProgram: - shaderCode's HashMap -> HashSet - adding HashSet for attached ShaderCode - link: allow relink, attachShader only if not yet attached - new add(gl, ShaderCode, ..) method, allowing compile/attach pre linkage - remove boxing of integer 'id', use generics style (warnings) - rename: glReplaceShader -> replaceShader, glUseProgram -> useProgram - fix: replaceShader - hashCode _is_ 'id' ShaderCode: - remove boxing of integer 'id', use generics style (warnings) - hashCode _is_ 'id' ShaderUtil: Use generics style (warnings), static names
