* some docs * rename a bunch of callbacks * more cleanup * format * last cleanup * some updates * more docs * done i think * name flag and format * name unused variable * comments * revert unwanted change * z64skin.h * format * Address review * Rename PostLimbDraw callbacks to PostDraw and some PR addressing * add true/false for setTranslation * ahhhh * remove "you" Co-authored-by: fig02 <fig02srl@gmail.com>
