8, currently. For some reason it took me a long time to think about
the rest of the path a character has to travel; I was just thinking in
terms of the 128 TGA writes done by rasops32_putchar() vs. the 24 done
by tga_putchar().

Absolutely. Again, this seems to be 100% wscons's fault. Does wscons
not have any such buffering?
