The gamepad mouse cursor has become THE mouse cursor. It is always visible and your real cursor is hidden, and this way the game can swap out other cursors for certain scenarios: * The Pencil Tool in the editor will use a pencil cursor over the level canvas. * The Flood Tool has a custom Flood cursor so you don't forget it's selected! Other improvements: * The Palette buttons in the editor now render using their swatch's pattern instead of only using its color. * If you have an ultra HD monitor and open a Bounded level in the editor which is too small to fill your screen, the editor canvas limits its size to fit the level (preferable over showing parts of the level you can't actually play as it's out of bounds). * The "brush size" box is only drawn around the cursor when a relevant tool is selected (Pencil, Line, Rect, Ellipse, Eraser)
