I am using gimp as my paint program for game graphics, but I want something that have auto straight tool, make the line straight, and isometric grid. I will like program for Sketching and low-poly art. It can also have stock photos and icons available. It should drag and move for animations. It should be free. It should have layers. Transparency of layer. Text function with lots of fonts.
Do you know some?
I am running Mac OS X.
