Change to checkCompilation

[orangebowlerhat]

The current output is busy and makes it hard to find the errors as the shader gets bigger. I modified a local version of pico with this -

checkCompilation() {
   if (!this.gl.getShaderParameter(this.shader, GL.COMPILE_STATUS)) {
     let log = this.gl.getShaderInfoLog(this.shader);
     let source = this.gl.getShaderSource(this.shader);
     let lines = source.split('\n');
     let errors = log.split('\n');
     let line = -1;
     errors.forEach (function (error) {
       let token = error.split(':');
       if (token.length > 3) {
         if (token[2] != line) {
           line = token[2];
           console.log(lines[line - 1]);
         }

         console.error(error);
       }
     });
   }
   return this;
 }

Which produces a more focused output.
