How do I create a magnifier?

This is a straight-up bitmap zoom. There may be better ways to this in C3. I am no expert.

For crisper results I would render in an off-screen buffer at multiples of the screen resolution and then copy the "magnified" image. No matter, all of this is rather resource intensive.

| Global number mag‎ = 3 + System: Every tick -> System: Take snapshot of canvas (PNG, quality 75, offset Mouse.X-50, Mouse.Y-50 size 100 x 100) -> MAG_PRINT: Load image from CanvasSnapshot (Resize to image size, cross-origin anonymous) -> MAG_PRINT: Set scale to mag + Mouse: On movement -> MAG_READ: Set position to (Mouse.X, Mouse.Y)
