Compositor for Windows 0.1.8

This independent Windows 11 x64 preview continues from 0.1.7. It is based on Compositor 1.0.4 by Robbie Tilton at a19db9011282399785dc18efcfded904627bdcc2. The port does not imply upstream endorsement, and full Mac equivalence is not claimed.

Rulers and guides

Horizontal and vertical rulers sit at the edges of the canvas and show document pixels. The numbers stay aligned with the image at fit, at actual pixels, and after zooming or panning. View → Rulers (Ctrl+R) hides or shows them. They are visible by default, and hiding them returns that margin to the canvas.

Drag from the top ruler to add a horizontal guide, or from the left ruler to add a vertical guide. Drag a guide to move it; its position is shown while the pointer moves. Releasing the pointer commits one undo step. Escape cancels the drag. Releasing a new guide back on its ruler, or releasing a guide outside the document on its axis, cancels it and leaves the document unchanged. Opening a project shows the guides saved in it. View → Guides shows or hides them and adds one at the vertical center when the document has none. View → Snap includes those guides while transforming.

Downloads are unsigned. Updates are manual. Full Mac equivalence, reciprocal .comp exchange, and Photoshop compatibility remain unverified. Keep a copy of each complete .comp directory. See KNOWN-ISSUES.md for brush performance, background removal, and the checks that have not been run on a fresh Windows install.
