Some did use the 160x100x16 graphics mode (using some of the same techniques in the OP) but one drawback is that they didn't always look 100% correct on clones, and some eventually broke when VGA cards came out.

My Columbia MPC clone didn't have the right character shape in the text-mode character rom, but I used the method for preview images of ray tracing code I experimented with in the '80's.
