Paint on Windows is getting layers and transparency support

With this update, we are introducing support for layers and transparency! You can now add, remove, and manage layers on the canvas to create richer and more complex digital art. To get started, click on the new Layers button in the toolbar, which will open a panel on the side of the canvas. Try changing the order of layers in this panel to see how the order of stacked image elements on the canvas changes. You can also show or hide and duplicate individual layers or merge layers together. We are adding support for transparency as well, including the ability to open and save transparent PNGs! When working with a single layer, you will notice a checkerboard pattern on the canvas indicating the portions of the image that are transparent. When working with multiple layers, if you erase content on one layer, you will reveal the content in layers underneath.
