 2x2 matrices have a lot of limitations :
 
 - all transformations are origin centered
-- they can’t provide basic transformations like translation
+- can’t provide basic transformations like translation
 - some transformations like scaling, etc. imply unwanted translations
 
-That’s why 3x3 matrices are a better choice ! See this repository
