Fixes:
- Should read `beginning` rather than `begining`.
- Should read `component` rather than `componnet`.
- Should read `projection` rather than `projeciton`.
- Should read `overridden` rather than `overriden`.
- Should read `anisotropic` rather than `aniostropic`.
- Should read `through` rather than `throuch`.
- Should read `associative` rather than `assocaitive`.
