Bugs:

1. Compile-time error line 99 vec syntax error fixed to vec2
2. Compile-time error line 99 normalize UV coordinates to [-1, 1] on both x and y axes
3. Compile time error line 102 raycast argument take in uv2 instead of uv
4. Runtime error line 11 iResolution.x changed to iResolution.y to get the length of the horizontal screen correctly
5. Runtime error line 75 change reflect argument from eye to dir to account for finding the direction of the ray bouncing off of the sphere and not a consistently valued ray
6. Runtime error line 18 change ray marching steps to double the amount of(64 to 128) so that the marching doesn't terminate early
