Hi,
I've just put a couple of grid-related patches in the tracker; I mention them here in case anyone wants to disagree ;-)
1. Anchor points are snapped to the grid; otherwise when you're drawing a line with the pen tool you get every point except the first snapped to the grid, which seems a little odd.
2. Resolve the issue whereby changing grid snap units from pixels to mm is not noticed. Fuller explanation is in the comments I added and in the patch tracker.
My other grid-related problem is that pasting a snapped object results in the pasted version not being snapped to the grid. I plan to fix this so that pasted objects are placed such that their points have the same offset from the nearest grid points as the original. Any objections?
Cheers
Carl
