* Added the colorbuffer patch with a small change due to SDL. Performance boost between 20-30% under OpenGL. * Improved the most renderers with setColor() function. * Fixed the genericrenderer, is now tested whether the images are in the viewport. * Fixed the gridrenderer, the grid is now drawn only up to the viewport. * Changed the vertex functions in opengl/renderbackendopengl.cpp from vertex3f() to vertex2f(). * Improved the Editor, now you can use blocking, grid and coordinate renderer over gui or keys. Additionally, the colors can be changed with the settings.xml.
