 # imageutils
 ## that is exactly image utilities, what i made for myself
 
-all the 2d graphics related stuff now moves there 
-
 ||(with a dummy as fuck image rescaling)||
 utilities work in theory, but doing everything very slow.
 i really love Go's image.Image interface type, but its really hard to do something with it well.
