Also covering the two variations for blitting only every second row or
blitting only a 320x200 quarter, as seen in the endings.
So yeah, there's indeed nothing wrong with piread.cpp. TH03 just uses that
separate function that only blits every second row of an image, and indeed
always loads the entire image as it would appear in a PNG conversion. Here's
what happens if you display these images using the non-interlacing function:

For 32-bit immediate values, PUSH by itself is enough. For everything else,
PUSHD works in both TASM and JWasm.
Also, could it be...? Could we actually move to JWasm without breaking the
build in TASM at all?
... and then I end up copying modified versions into the individual game
subdirectories after all, because the changes between games were simply too
drastic. (That's also why I'm counting pfopen() itself twice.)
Only one slice left now, and then we're done with reduction!
