this is very embarassing to ask about for me but does anyone in my audience understand why Apple's CGAffineTransform is defined as mapping to a matrix where the last column is (0, 0, 1) and the last row is (tx, ty, 1.0); shouldn't it be the other way around? when does this work?

wait. is it just one system uses multiplication by a column vector and the other uses multiplication by a row vector. does that mean that the matrices are equivalent if transposed. is that the monster that's haunted me for checks notes two years? if so then (brb killing myself)

‪i have this horrible feeling that i came very close to realising this a year ago already and instead blamed myself‬
