Stroke alignment selection bug

[pencilking2002]

Stroke layers that have alignment set to "inside" are difficult or impossible to select with the mouse.

Steps to reproduce:

1. Create a stroke layer by using the pen tool. Make sure to not have any fill on it
2. Select the stroke and in the properties panel, set it's alignment to "inside"
3. Notice that it becomes difficult to select/move with the mouse
4. This effect is even more exegerated if you there is a fill layer behind the stroke
5. Place a fill layer behind the stroke layer and try to select the stroke...it is not possible

When using StrokeAlign::Inside, the stroke width is set to zero for some reason?

Graphite/node-graph/libraries/vector-types/src/vector/style.rs

Lines 474 to 481 in 2c29d2c

	pub fn effective_width(&self) -> f64 {
	self.weight
	* match self.align {
	StrokeAlign::Center => 1.,
	StrokeAlign::Inside => 0.,
	StrokeAlign::Outside => 2.,
	}
	}

The stroke width is attached to click targets:

Graphite/node-graph/libraries/rendering/src/renderer.rs

Line 1494 in 2c29d2c

let stroke_width = vector.style.stroke().as_ref().map_or(0., Stroke::effective_width);

This is then used as the side length for the square for the intersection of the outlines:

Graphite/node-graph/libraries/vector-types/src/vector/click_target.rs

Line 315 in 2c29d2c

let target_bounds = [point - DVec2::splat(self.stroke_width / 2.), point + DVec2::splat(self.stroke_width / 2.)];

It is in fact possible to select with the select tool by clicking on the line, however there will be no hover outlines. This is because the actual selection logic has some additional tolerance:

Graphite/editor/src/messages/tool/tool_messages/select_tool.rs

Lines 556 to 557 in 2c29d2c

	let tolerance = DVec2::splat(SELECTION_TOLERANCE);
	[self.drag_start - tolerance, self.drag_start + tolerance]

I hope that clarifies that it is in fact possible but somewhat annoying due to questionable choices.
