SM.Base: ~ Improved Keyboard.AreSpecificKeysPressed(int, int) ~ Made GenericTransformation.LastMaster's set public ~ Made the fixed update use the property "IsExiting" to determent if it should stop. ~ The MainFramebuffer of each RenderPipeline now has always a name. SM2D: ~ Moved the checking code of Mouse2D.MouseOver into a own method.
