-	CRT simulation shadowmask style, I also have a trinitron version
-	optimized for 4X scaling on a ~100ppi display.
-
-	The "Scanlines" seen in the simulated picture are only a side effect of the phoshor placement
-	and decay, instead of being artificially added on at the last step.
-
-	I have done some testing and it performs especially well with "hard" input such a faked
-	(dither based) transparency and faked specular highlights as seen in the bigger sprite.
-	A version tweaked and made for 4k displays could look pretty close to the real thing.
