nmlgc 18757c33f9 [Maintenance] [th01] Use a common macro for sloppy unblitting of 8×8 sprites
… treating them as conceptually the same thing allows us to deduplicate

nmlgc 308b73524d [Maintenance] [th01] Merge invincibility sprites into the regular 8×8 shapes
They have the same size, their hardcoded sprites are stored next to
each other in the code, and…

nmlgc 3c008b6a4f [Decompilation] [th01] Invincibility sprite blitting
In which ZUN accidentally the GRCG rather than the EGC in what should
have been (?) the unblitting function. Which then ends up actually
blitting yet another randomly background-masked version of the same
sprite on top of the old one. And after just a few frames, you get
those fully filled red diamonds you don't see in the sprite sheet.

Then again, if the 16w×h rectangle unblitting function is all you
have, and you can't be bothered to actually learn the EGC, this *is*
the better option 🎺

nmlgc 23f5645be5 [Decompilation] [th01] Ellipse arc blitting
Most frequently used for complete circles, though… but who cares, as
of this commit, ReC98, as a whole, is ⅓ done!
