* Reworked scissor tests to remove fixme and handle issues with intel gpu's * Error handling for scissor tests * Disable strict opengl by default * Reformatting for JD * Updated scheme for new property in config * Fixed typo * Moved magic value to constant. I liked the magic :( * Fixed ordering for undertale * Fixed undertale bug * Removed strict opengl in favour of required. With this an exception is no longer thrown, just a warning for required extensions * Uses clamp instead of if's * Removed evil tabs and no longer used include
