reading the official GLSL specification this should be done by using mat3x3

mat3x3(mat4x4); // takes the upper-left 3x3 of the mat4x4

however when i just change mat3 to mat3x3 i get this:

ERROR: 0:36: 'mat3x3' : no matching overloaded function found

had no luck with this, if i set it to uniform it complains that i cant assign to it because it is uniform
