+/* 
+Simple pixel perfect scanlines for use *only* with interger scaling mode. 
+Perfect for low res output and low performance machines.
+Also great if you dont want any moire patterns pin sharp scanlines 
+Use in combination with HDR mode in latest RetroArch and very bright 
+HDR monitors to get 'glowing' scanlines much like the original CRT's but sharper 
+
+Recommended setting for 720p 1 pixel width scalines at 2x or 3x scalings
+Recommended setting for 1080p 2 or 3 pixel width scalines at 4x or 5x scalings
+Recommended setting for 4K 4 or 5 pixel width scalines at 8x or 9x scalings
