[Reverse-engineering] [th05] Masked PI display As used for the title screen fade-in effect. Another function that apparently was deliberately written to run not that fast, by blitting each row individually to the 400th VRAM row just so that it can then turn on the EGC, perform the actual masked blit to the VRAM destination, and then turn the EGC off before moving to the next now. The same effect could have entirely been accomplished by copying graph_pack_put_8() and applying the mask there; it's not like ZUN didn't know how to modify master.lib… (See also 44ad3eb4) --Nmlgc 2019-12-10 07:52:24 +00:00			`public _PI_MASKS`
