This eliminates the precision issues caused by the projected texture by setting the .w coordinate to a constant value. I decided to keep the projected sampling itself around to demonstrate that d3d doesn't do anything special with the 3rd and 4th value like it does with other shadow formats
The 3rd and 4th coordinate are going to be the same for the locations you're sampling now.
