~ Moved code around in files. SM.Base: + PostProcessing-system + OnInitialization() for Scenes. + Shader-Extensions + Added option to not react while unfocused to the window. + Added Screenshots to the window. + Connected the log system to the SM.OGL-action system. ~ Replaced IShader with abstract MaterialShader. ~ When a log compression folder doesn't exist, it will create one. SM.OGL: + Added support for UniformArrays + Added ShaderPreProcessing + Added Shader Extensions. + Added Debug actions. + SM.OGL settings ~ Framebuffer Size is automaticly changed, when the window and scale is set. SM2D: + Added easy shader drawing.
