Placed line templates are offset by half a square

[olilan1]

When placing a line template from a spell or from an action, the template seems to jump by half a square when placed, either vertically or horizontally. If it jumps horizontally, the coloured part of the template ends up being double height (two squares high). If it jumps vertically, the template ends up one square too big on either end.

No matter how you place it originally, it always ends up offset like this - it doesn't seem possible to make the template cover the right number of squares.

Seen on Foundry 12.329 and PF2e 6.1.1, but note that this issue was mentioned by someone on the system Discord on 2nd Dec 2023 - also see there for a video.

Btw, tested with no modules and it still happens. Tested with Lightning Bolt (120' line), Grim Tendrils (30' line), and Lightning Dash (an action rather than a spell), all showed the same behaviour.

So it seems this bug isn't new, but it was looser before allowing it to be placed correctly:

Placing it like this in 6.0.4

would cause this occur:

We can restrict it to corners and edges, and the behavior should become correct
