These could have been nicely separated into per-device translations
(one for GDC, one for EGC, one for regular VRAM accesses)… if their
original order followed that classification.
OK, so let's make it one full `graph_ex.cpp` translation unit… nope,
FUUIN.EXE needs graph_2xscale_byterect_1_to_0_slow() with different
compilation flags. 🤦
Whatever, fuck it, let's go for individual translation units, with
individual headers, so that we at least get predictably organized
source code out of this.

Well well, the choice between sorting this function mechanically (and
putting it next to the EGC functions) or contextually (and putting it
next to the GDC SCROLL function)… Any choice would eventually turned
out suboptimal, I'm sure. 😅
