Guidelines offset

[Dreadrith]

The guide lines in the hierarchy seem to be off center on higher resolution monitors. My own screen is small and it wasn't easy to visualize differences since my own monitor displays it correctly. My own attempts just made it even more off center. The line drawing code already draws at the 1/2 locations such as offsetting left by 16/2 (size of the foldout icon) and offsetting down by half the height of the Rect it's in so I'm unsure what other approach should be done.

If I change https://github.com/Dreadrith/HierarchyPlus/blob/1eb5350be1cd14fd686b33faae41e47d14542f7e/Editor/HierarchyPlus.cs#L269 to 13, it gets very close. 13.5 would probably make it look correct, but I can't use decimals there. Same for Line 294, second value. If it was 11.5 it would probably just align.

This is at 13/11

270 (34 -> 33) 308 (8 -> 7)

For all of those, I need an additional 0.5 to get it to look centered.

Issue: Incorrect Math Calculation

The current math logic is incorrect. update the code at lines 335-337 to the following:

float marginWidth = hasChildren ? 14.0f : 1.9f;
float lineWidth = 14.0f * depth + 33.9f;
Rect lineRect = new Rect(rect.x - lineWidth, rect.y, lineWidth - marginWidth, rect.height);

By using float instead of int for width and height, the calculation becomes more precise and gives better results.

update the code at line 369 to this for more accurate round corners:

Vector3 middlePoint = new Vector3(basef - extraWidth - 7, rect.height / 2);
