Pull request overview
Adjusts the multiline trapezoidal grid (used for Grid infill when multiline > 1) to make the generated pattern symmetric, addressing a visible centering/misalignment artifact.
Changes:
- Updates the trapezoid row point construction to be symmetric around the period midpoint.
- Removes the extra translation applied after transposing points on alternating infill layers.
- Updates the inline geometry diagram/comments for the trapezoidal grid.

Description
Correction of the centering of the multiline infill grid; I have adjusted the points, so the pattern is now symmetrical, thereby correcting a slight misalignment that this infill had.
