Paint

Everything happens on this canvas in your browser. Nothing is uploaded. Opening an image loads it onto the canvas as a flat background; there are no layers. The slashed swatch next to Border or Fill is transparent, so that part isn't painted and whatever is already on the canvas shows through. Text tool: pick it, click where you want the text, and type. Click away to place it, Escape to cancel. Zoom: scroll wheel over the canvas, or the magnifier (click to zoom in, Alt+click or right-click to zoom out). Middle-drag to pan. Ctrl+0, or click the magnifier again, to fit.
