 ## Clipping
 
 There are 3 clipping stages, 2 clipping stages in 3D space against zfar and znear and 1 clipping
-stage in 2D againts left,bottom,right,top(2D image bounds).
+stage in 2D against left, bottom, right, top(2D image bounds).
 
 First the triangles get clipped against the zfar plane,
 if a triangle has even one vertex outside the clipping region, the entire triangle gets cut.
