I'm using the djgpp port of gnuplot---it's very nice.  The readme.dj2
doc says that two options (among others) for the GRX20DRV environment
variable (used by the GRX-2.3 graphix library) are

SET GRX20DRV=VESA  gw <width> gh <height> nc <colors>

SET GRX20DRV=stdvga  gw <width> gh <height> nc <colors>

OTOH the `set terminal' command in gnuplot accepts `svga' but
does not recognize `VESA'.

Can someone explain to me the difference between stdvga and VESA
(I know what the acronyms stand for :), and when one would be
preferred over the other?

The only video driver information I can provide is what I see
at boot time:
